Question

Which expression represents the volume of this solid ?

Answer 1

Answer:

The answer is option 5.

Step-by-step 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 :

$v = \frac{1}{3} \times \pi \times {r}^{2} \times h$

Let r = 4,

Let h = 12,

$v = \frac{1}{3} \times \pi \times {4}^{2} \times 12$

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