Question

14. The diameter of a cylinder is 7 feet, and the height is 12 feet. What is the volume of the cylinder in terms of л? Recall that the volume formula for a cylinder is V = r²h.

​

Answer 1

The formula is V = r²h for the volume of a cylinder, we need to first find the radius of the cylinder:

The diameter of the cylinder is 7 feet, so the radius is half of that cylinder, so you have to divide by 2 to get half of the diameter:

r = 7/2

= 3.5 feet.

V = π(3.5)²(12)

V = π(12.25)(12)

V = 147π

Therefore, the volume of the cylinder is 147π cubic feet.
