What is the volume of the cone? cone v = one-third b h startfraction 70 over 3 endfraction pi centimeters cubed startfraction 14
Bas_tet [7]

Using the assumed values, the volume of the cone is V = \frac {250}3\pi

<h3>How to determine the volume of the cone?</h3>

The volume of a cone is calculated using:

V = \frac 13\pi r^2h

The parameters are not given.

So, we use the following assumed values

Radius, r = 5

Height, h =10

Using the assumed values, we have:

V = \frac 13\pi * 5^2 * 10

Evaluate the product

V = \frac {250}3\pi

Hence, using the assumed values, the volume of the cone is V = \frac {250}3\pi
