Question

Not sure if i chose the right one?

Answer 1

Answer:

113.04 ft³ is correct

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = $\frac{1}{3}$πr²h ( r is the radius and h the height )

There are 2 cones to be summed one with h = 7 , the other with h = 5

Thus

V = $\frac{1}{3}$ π × 3² × 7 + $\frac{1}{3}$π × 3² × 5

   = $\frac{1}{3}$ × 3.14 × 9 (7 + 5)

   = 3.14 × 3 × 12

   = 113.04 ft²
