HURRY I NEED HELP PLS

Find the volume of each solid. Round to the nearest tenth if necessary.

Answer 1

3,454 cm³

Explanation:

This is a cylinder so the volume formula is
`V=\pi r^(2) h`

The problem gives us the diameter (20 cm) and the height (11 cm). Since the formula uses the radius instead of the diameter, we have to divide the diameter by 2.

20 ÷ 2 = 10

The radius is 10 cm

Now, we plug our height and radius into the formula to find the volume.

`V=\pi r^(2) h\\V=((22)/(7))(10)^(2)(11)\\V=((22)/(7))(100)(11)\\`

V≈3,454
