Question
What is the approximate volume of the cylinder?
Answer options with 5 options
A.
251.2 inches cubed
B.
502.4 inches cubed
C.
879.2 inches cubed
D.
1,256 inches cubed
E.
5,024 inches cubed
To find the volume of a cylinder, we use the formula V = πr^2h, where r is the radius and h is the height.
Given that the diameter is 20 inches, we can find the radius by dividing the diameter by 2: r = 20 / 2 = 10 inches.
Substituting the values into the formula, we get V = 3.14 * 10^2 * 4 = 3.14 * 100 * 4 = 1,256 inches cubed.
Therefore, the approximate volume of the cylinder is 1,256 inches cubed.
The correct answer is D. 1,256 inches cubed.
