Question

Which expression represents the volume of this solid ?

Answer 1

The answer is option 5.

Explanation:

The formula is V = 1/3×π×r²×h where r represnt radius and h is height. Given that the diameter of cone is 8 inches so the radius is 4 inches then substitute the value into the formula :

`v = (1)/(3) * \pi * {r}^(2) * h`

Let r = 4,

Let h = 12,

`v = (1)/(3) * \pi * {4}^(2) * 12`

`v = \frac{( {4}^(2)\pi)12 }{3}`
