Question

A cylinder has a base diameter of 8 inches and a height of 7 inches. What is its volume in cubic inches, to the nearest tenths

place?

Answer 1

351.9 cubic inches

Explanation:

The volume formula for a cylinder is:

`V=\pi r^(2) h`

r is the radius

h is the height

To find the radius, we simply divide the diameter by 2 since the radius is have of the diameter. This will give us 4. Now we just put our values into the formula and solve with a calculator:

`V=\pi (4^(2)) (7)\\V=\pi 16(7)\\V=\pi 112\\V=351.85\\`

The rounded number is 351.9
