Answer:
16pi cm^2, 112pi cm^3, 351.68 cm^3
Step-by-step explanation:
Given: Height=7cm, radius=4cm
1. The base is a circle and Area of circle = pi * r^2
Plug in the radius to get --> A = pi * (4cm)^2 = 16*pi cm^2
2. This is asking for the volume of the cylinder.
Volume of cylinder is V=h*pi*r^2 --> 7cm * pi * (4cm)^2 = 112 pi cm^3
3. Just plug 3.14 into pi --> 112 * pi cm^3 = 351.68 cm^3

Answer:
2970
Step-by-step explanation:
I hope it helped :) if it didnt just message me since in confused whats the dot between the 6.3 and 10²
Answer:
2.97*10^3
Step-by-step explanation:
You have to solve it first so you have 2970 as your answer but you want it in scientific notation. To do this put the decimal after the first number this gives you 2.970. Whenever you need to make the number bigger you use a positive power and whenever you want to make a number smaller you use a negative power. The amount of powers the 10 gets is the amount of times you move it over. You have 2.970 and to get to the original number you need to move it 3 places to the right. Going to the right with your decimal makes it bigger which what you want, so you have 2.970*10^3 as your answer.

These figures are similar. The perimeter and
area of one are given. The perimeter of the
other is also given. Find its area and round
to the nearest tenth.
Perimeter = 20 m
Area = 19.6 m2
Perimeter = 34 m
Area = [? ]m2
Enter
Answer:
56.644 m^2
Step-by-step explanation:
It's a rule that if the ratio of the sides of 2 similar figures is a:b, the ratio of their areas is a^2:b^2. (I may not be using the standard variables or the exact wording here, but that's the basic idea.)
You can simplify this and understand it with squares. All squares are similar, right? Imagine a 2 in. by 2 in. square and a 4 in. by 4 in. square. The ratio of their sides is 2:4, or 1:2. (The ratio of their perimeters is the same thing. 2*4=8 inches for the smaller square, and 4*4=16 for the bigger square. 8:16=1:2) The ratio of their areas is 4:16, or 1:4. (1/2)^2=1/4
The same thing applies here. The perimeter of the larger figure divided by the perimeter of the smaller one is 34/20=1.7. That means that the area of the larger figure divided by the area of the smaller one is 1.7^2, or 2.89. You can write an equation where x is the area of the larger one:
x/19.6=2.89
x=56.644 m^2

From a board that was 2 meters long Collin cuts off a piece 1.67 meters long How long was the piece
Answer:
0.33 m
Step-by-step explanation:
The original board length was 2 m. If we cut off a piece 1.67 m long and want to know the length of the remaining piece, we determine that by subtracting 1.67 m from 2 m, obtaining 0.33 m

What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second.
Answer:
1
Step-by-step explanation:
What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second?
3 consecutive angles
= x, x + 1, x + 2
We are told in the question that:
the sum of the first and third is equal to three times the second
a + c = 3b
x + x + 2 = 3(x + 1)
2x + 2 = 3x + 3
3x - 2x = 2 - 3
x = -1
The largest of the three numbers is the third number
= x + 2
x = -1
x + 2 = -1 + 2
The third and largest number is 1

Solve the triangle using the Law of Sines. (Assume a = 7.1, b = 2.9, and ∠A = 70°. Round the length to one decimal place and the angles to the nearest whole number.)
Answer:
sides
a=7 (rounded)
b=3 (rounded)
c=8 (rounded)
angles
A=70
B=22.57
C=87.43
Step-by-step explanation:
a . given
b . given
c = a·sin(C)/sin(A)=7.54806
A . given
B = arcsin (b·sin(A)/a) = = 0.39393 rad = 22.57° = 22°34'13"
C = 180° - A - B = 1.52593 rad = 87.43° = 87°25'47"
LAST ONE!!! PLZ HELP!!
Answer:
x = 10°
y = 25°
Step-by-step explanation:
3x = 5x - 20 because they are alternate interior angles
subtract 5x from each side of the equation:
-2x = -20
Divide both sides by -2:
x = 10°
The sum of the interior angles of any triangle = 180°
2y + 4Y + (5x - 20) = 180°
combine like terms:
6y + 5x - 20 = 180°
add 20 to each side:
6y + 5x = 200°
substitute for x:
6y + 5(10) = 200°
subtract 50 from each side:
6y = 150°
divide both sides by 6:
y = 25°
Find the measure of the indicated arcs or central angles in OA. DG is a diameter.
Answer:
Arc DE = 90°
m<GAB = 82°
Arc DC = 49°
Step-by-step explanation:
Given:
m<EAF = 74°
m<EAD = right angle = 90°
Arc BG = 82°
Required:
Arc DE,
<GAB, and
Arc DC
Solution:
Recall that the central angle measure = the intercepted arc measure.
Therefore:
✔️Arc DE = m<EAD
Arc DE = 90° (Substitution)
✔️m<GAB = arc BG
m<GAB = 82° (Substitution)
✔️Arc DC = m<CAD
Find m<CAD
m<CAD = ½(180 - m<GAB)
m<CAD = ½(180 - 82)
m<CAD = 49°
Arc DC = m<CAD
Arc DC = 49°
HELP ME ASAP!!!!!!!
Happy Easter
see pic attached
good luck
Answer:
D
Step-by-step explanation:
m + 9 can be +ve or -ve or 0.
m can be any number, even lesser than -9 to make it +ve. [-10+9 = -1 = -ve no.]
Or, maybe greater than -9 to make m+9 +ve. [-8 + 9 = 1 = +ve no.]
Or, maybe -9 only so that m+9 is 0
[ -9 + 9 = 0 ]
It can be -ve, +ve and 0 as well.
Answer:
D
Step-by-step explanation:
M could be -1
and -1 + 9 = 8 , positive
.
M could be -9 too
-9 + 9 = 0, zero
.
M could be -10
-10 + 0 = -1 negative

Which expression is equivalent to
2x +3 - 3x + (-2)
A x + 5
B 12
12x - 1
x + 1
D 1 - 1
Answer:
-x + 1
Step-by-step explanation:
First, rewrite 2x +3 - 3x + (-2) as 2x +3 - 3x - 2. Note that +(-2) = -2.
Next, combine like terms. We get -x + 1.

Write (-0.6) (-0.6).(-0.6) using exponents
Answer:
(-0.6)^3
Step-by-step explanation:
Here, we want to write the given expression in exponential terms
From what we have, there is a repetitive term
For example, if we had;
(x)(x)(x)
Exponentially, we will have this written as x^3
Using the above technique in what we have at hand
(-0.6)(-0.6)(-0.6) = (-0.6)^3
