2*22/7*14*21
1548 cm2
iii) total surface area=2 pie r(r+h)
2*22/7*14(14+21)
2780
iv) volume of cylinder=pie r2h
22/7*14*14*21
12936 ans
Step-by-step explanation:
Answer:
As = 2112 cm²
Step-by-step explanation:
given:
A cylinder has a circular base radius 14cm and height of 10cm.
find:
the total surface area of the cylinder. [take pie 22/7] *
solution:
surface area (As) = 2πrh + 2πr²
where r = 14 cm; h = 10 cm; π = 22/7
plugin values into the formula:
As = 2 (22/7) 14 (10) + 2 (22/7) 14²
As = 880 + 1232
As = 2112 cm²
6(1 + 5n) − 6n = 174
Answer:
N=7
Step-by-step explanation:
1. Distribute the 6 into the parentheses
6+30n-6n=174
2.combine like terms
6+24n=174
3. Subtract 6 on both sides
24n=168
4.now divide
24/24 cancels out 24/168 is what 7 soooo

I need help with this solving equations X + 9 = -16
Answer:
Step-by-step explanation:
x + 9 = -16
Subtract 9 form both sides
x + 9 - 9 = - 16 - 9
x = -25
Answer:
X= -25
Step-by-step explanation:
Subtract 9 from both sides.
-3(4a + 3) + 4(6x + 1) = 43
Answer:
-3(4a+3)+4(6x+1)
12a+(-9)+24x+5
12a-4+24x
Step-by-step explanation:
Because you can't add 12a & 24x bc they're different variables ( a & x ) & -9+5 you always minus it and it's going to be a negative because -9 is bigger than 5

hey how do i solve this problem i’m clueless and don’t know how to do it. if you can could you explain it please?
(6g^4h^5)^2. We have to square each term individually. Remember, squaring an exponent is just multiplying the exponents together.
6^2 = 36
(g^4)^2 = g^8
(h^5)^2= h^10
The final answer: 36g^8h^10
The midpoint of segment AB is (1,4). The coordinates of point A are (-2, -3). Find the coordinates of point B.
A)
(3,7)
B)
(4, 11)
(4, -10)
D)
(-5, -10)
Answer:
B) (4,11)
Step-by-step explanation:
Plot the points and count how far point A is to the midpoint.The rise is 7 and run is 3 so count 3 right and 7 up from point AB to get B.
-3x + y = 22
-12x – 10y=-10
Answer:
x = -5, y = 7Step-by-step explanation:
-3x + y = 22 ⇒ y = 3x + 22
-12x - 10y = -10 and y = 3x + 22
-12x - 10(3x + 22) = -10
-12x - 30x - 220 = -10
+220 +220
- 42x = 210
÷(-42) ÷(-42)
x = -5
y = 3(-5) + 22 = -15 + 22 = 7

How do I find the domain and range of a graph?
The domain is the x-axis and the range is the y-axis.
To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.
To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.

Find three equivalent fractions for 2/3 by multiplying by 3/3, 5/5 and 6/6. What property of multiplication do we use to find equivalent fractions?
The equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
2/3 by multiplying by 3/3, 5/5, and 6/6.
= (2/3)(3/3)
= 6/9
= (2/3)(5/5)
= 10/15
= (2/3)(6/6)
= 12/18
The multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.
The numerator and denominator of a fraction are multiplied by the same number for determining equivalent fractions.
Thus, the equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

A little help here thank you!!!
Answer:
∠B = 82°
Step-by-step explanation:
(see attached for reference)
recall the property that an exterior angle of a triangle is equal to the sum of its two remote interior angles.
in our case, the exterior angle is obtuse ∠A = 143°
the two remote interior angles are ∠C and ∠B
hence according to our definition above:
143° = ∠C + ∠B (we are given that ∠C =61°)
hence
143° = 61° + ∠B
143° - 61° = ∠B
∠B = 82°
Write an equation of the parabola in intercept form that passes through (-2,0.05) with x-intercepts of -7 and -3.
Answer:
y = 0.01(x +7)(x +3)
Step-by-step explanation:
For intercepts p and q, the equation will be ...
y = a(x -p)(x -q)
For the given intercepts, the equation is ...
y = a(x +7)(x +3)
We can find the value of 'a' by using the given point:
0.05 = a(-2+7)(-2+3) = 5a
0.01 = a . . . . divide by 5
The complete equation is ...
y = 0.01(x +7)(x +3)

what is the gradient of the line 3x+y=4
Answer:
The slope is - 3Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
The equation is 3x+y = 4
To find the slope of the line we must first write the equation in the general form above
Make y the subject
That's
y = - 3x + 4
Comparing with the general equation above
Slope of the line = - 3

Find the domain and range of the following absolute value functions. fx)=|x-1|+2 I’ll mark brainliest to whoever answers first
Answer:
Domain is All Real x.
Range is f(x) ≥ 2.
Step-by-step explanation:
The vertical lines about the x - 1 means the Absolute value ( always positive).
|x - 1| will always be positive or 0 and it's graph is shaped like a V with the vertex at (1, 0)
The + 2 will move the graph up 2 units so the vertex becomes (1, 2).

X
C
E
F
(b) B. I, and I are distinct points that are collinear.
(c) Another name for plane X is plane I.
(d) E, I, I, and I are distinct points that are coplanar.
Answer:
a) FC ←→ and BD ←→ are distinct lines that intersect.
b) B , C and D are distinct points that are collinear.
c) Another name for plane [tex]X[/tex] is plane AEF.
d) E , A , F and C are distinct points that are coplanar.
Step-by-step explanation:
The first step to solve this question is to look carefully at the picture.
For a) :
We can see that the line FC and the line BD intersect at the point C.
We can write :
a) FC ←→ and BD ←→ are distinct lines that intersect (we can see more lines that intersect with FC ←→ in the picture such as AC ←→ or AE ←→).
For b) :
We can see that the line BD ←→ passes through the points B , C and D (B , C and D are collinear points).
We can write :
b) B , C and D are distinct points that are collinear.
For c) :
We can name any plane using three points which are contain in the plane but this three points must not be collinear points.
We can name the plane [tex]X[/tex] using the points A , E and F (this is a possible solution).
We can write :
c) Another name for plane [tex]X[/tex] is plane AEF.
Finally, for d) :
Two or more points are coplanar wherever they belong to the same plane.
In the picture, the points A , E , F and C belong to the plane [tex]X[/tex].
We can write :
d) E , A , F and C are distinct points that are coplanar.

16x-8x-12= 24+20
(16x-8x)-12= 24 +20
8x - 12= 24 +20
8x = 24+ 20 + 12
8x = 54
x = 54/8
x= 7
Answer:
x=7
Step-by-step explanation:
1. combine like terms
2. isolate x
3. divide by 8 to get x
what is the answer to -3x+5= -16
Answer: 7
Step-by-step explanation: First you subtract 5 from both sides to single out the -3x. Then you will have -3x = -21. You will then divide both sides by negative three because you want to single out the x. After that, you will have the answer of x = 7
Answer:
x = 7
Step-by-step explanation:
-3x+5=-16
-5 -5
-3x=-21
-3x/3 = -21/-3
x=7
There are 28 butterflies in the garden. Some are blue and some are yellow. If b represents the number of blue butterflies in the garden, which expression represents the number of yellow butterflies in the garden?
Answer:
y = 28 - b
Step-by-step explanation:
you can find the number of yellow butterflies, y, by subtracting the number of blue butterflies, b, from the total number of butterflies which is 28.
