Question

Find the volume of each cylinder round to the nearest tenth use 3.14 ​

Answer 1

`\large\boxed{V\approx2122.6\ cm^3}`

Explanation:

The formula of a volume of a cylinder:

`V=\pi r^2H`

r - radius

H - height

We have r = 6.5 cm and H = 16 cm. Substitute:

`V=\pi (6.5)^2(16)=\pi(42.25)(16)=676\pi\ cm^3`

`\pi\approx3.14`

`V\approx676\cdot3.14=2122.64\ cm^3\approx2122.6\ cm^3`
