Question

Find the volume of the cone. Use u = 3.14. Round to the nearest hundredth.

785.0 cm
7850.0 cm
2616.67 cm
261.67cm

Answer 1

261.67 cm³

Explanation:

The formula of a volume of a cone:

`V=(1)/(3)\pi r^2H`

r - radius

H - height

We have r = 10cm and H = 25 cm.

Substitute:

`V=(1)/(3)\pi(10^2)(25)=(1)/(3)\pi(100)(25)=(250\pi)/(3)\ cm^3`

`\pi\approx3.14\to V\approx((250)(3.14))/(3)\approx261.67\ cm^3`
