A company makes steel rods shaped like cylinders. Each rod has a radius of 3 centimeters and a height of 20 centimeters. If the company used 45,781.2 of steel, how many rods did it make?
Answer:
80 rods of steel.
Step-by-step explanation:
Here is the complete question
A company makes steel rods shaped like cylinders. Each rod has a radius of 3 centimeters and a height of 20 centimeters. If the company used 45,781.2 cm³ of steel, how many rods did it make?
Solution
Since the steel rod is a cylinder whose volume, V = πr²h where r = radius of cylinder = 3 cm and h = height of cylinder = 20 cm.
We substitute these into V to find the volume of one rod.
So, V = πr²h
= π(3 cm)² × 20 cm
= π × 9 cm² × 20 cm
= 180π cm³
= 565.49 cm³
Since 45,781.2 cm³ of steel was used, this total volume of steel, V' equals the number of rods, n times the volume of one rod, V.
So, V' = nV
Making n subject of the formula, we have
n = V'/V
Substituting V' and V into the equation, we have
n = 45,781.2 cm³/565.49 cm³
n = 80.96
We round n = 80.96 down to 80 since we cannot have a decimal number of rods.
So, n = 80 rods
So, the company made are 80 rods of steel.

Answer:
240
Step-by-step explanation:
1. Area of two small triangles (OR one big) + Area of rectangle
2. Triangle
A(t) = 4*10 = 40 [4*10/2 + 4*10/2]
3. Rectangle
A(r) = 20*10 = 200
4. Combined Area
40+200=240
Step-by-step explanation:
So this figure has two parts:- A triangle and a rectangle
We can first solve area of Triangle
[tex] = \frac{1}{2} bh[/tex]
So the base is 20 and height is 4
[tex] \frac{1}{2} \times 20 \times 4 \\ = 10 \times 4 \\ = 40[/tex]
Now the area of rectangle
[tex] = l \times b[/tex]
Length is 20 and breadth is 10
[tex]l \times b \\ 20 \times 10 \\ = 200[/tex]
So the total area is 200 + 40 which is equal to 240

A cylinder has a height of 2 millimeters. Its volume is 6.28 cubic millimeters. What is the
radius of the cylinder?
Answer:
r = 1
Step-by-step explanation:
V= πr^2h
π= 3.14
6.28= πr^2(2)
(6.28)/ (2π) = r^2
1 = r^2
r = 1

In triangle EFG, the measure of angle E is 97 degrees, and the measure of angle F is 15 degrees. What is the measure of angle G?
Answer:
Measure of angle G is 68°.
Step-by-step explanation:
In triangle EFG,
Measure of angle E = 97°
Measure of angle F = 15°
By the triangle sum theorem,
Sum of measures of all interior angles of triangle = 180°
m(∠E) + m(∠F) + m(∠G) = 180°
97° + 15° + m(∠G) = 180°
m(∠G) = 180° - 112°
= 68°
Therefore, measure of angle G is 68°.

Answer:
154
113.04 in
Step-by-step explanation:
Area of a circle = Tr²
Circumference of a circle = 2Tr
T = 3.14
r = radius
The radius has to be determined to calculate the area of the circle
43.96 in = 2 x r x 3.14
r = 43.96 in / 2 x 3.14
= 7 in
Area = 3.14 x 7² = 153.86 in = 154 in²

Answer: 72
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
Circumference of a circle = 2πr
Area of a circle: πr^2
Plug in:
C = 2πr
30.1 = 2(3.14)r
30.1 = 6.28r
r = 4.79 (Dividing both sides by 6.28)
Use area of the circle:
A = 3.14(4.79)^2
= 72.044474
Round to nearest whole number = 72
in the diagram below,the angle of depression from P to Q is 45.which of the following is closest to the distance between P and Q
Using relations in a right triangle, it is found that the distance between Q and T is given by:
[tex]h = 32\sqrt{2}[/tex]
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.Researching the problem on the internet, it is found that:
The side opposite to the angle of 45º is of 32 feet.The hypotenuse is the distance between P and Q.Hence:
[tex]\sin{45^\circ} = \frac{32}{h}[/tex]
[tex]\frac{\sqrt{2}}{2} = \frac{32}{h}[/tex]
[tex]h = \frac{64}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]h = 32\sqrt{2}[/tex]

Answer:
h=14
Step-by-step explanation:
So since the triangular shape is a right triangle, we can use a Pythagorean triple. For this question, lets use (5,12,13). But, if you just want to use the formula:
5^2+x^2=13^2
25=x^2=169
x^2=144
x=12
That means a part of h is 12. BUT, we also have an extra two ft on top of the triangle, so h=12+2=14.

it's asking to write an equation in slope-intercept form for the line with slope -4 and y-intercept 7. then graph the line. please help
Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)
h(j + i) - k5 + h

pls put how you did it
Answer:
16
Step-by-step explanation:
First you want to plug in all the numbers where the letters are
h ( j + i )- k(5) + h
3 ( 2 + 4 )- 1(5) + 3
After this step you will have to distribute the 3 outside the parenthesis. Which you do by multiplying everything in side the parenthesis by the outside number which is three.
6 + 12 - 1(5) + 3
Then you just follow PEMDAS to solve for the rest
6 + 12 - 5 + 3
18 - 5 + 3

Answer:
The correct answer is C.
Please help what's the answer
Answer:
The answer is going to be No, (-1, 2) is only a solution for the equation 2x + 5y = 8
Let's find out if it is a solution first:
3 x -1 - 2 x 2 = -3 - 4 = -7
2 x -1 + 5 x 2 = -2 + 10 = 8
From this, you can tell that (-1, 2) is only a solution to 2x + 5y = 8
