Answer:

113.04 ft³ is correct

Explanation:

The volume (V) of a cone is calculated as

V =
(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 =
(1)/(3) π × 3² × 7 +
(1)/(3)π × 3² × 5

=
(1)/(3) × 3.14 × 9 (7 + 5)

= 3.14 × 3 × 12

= 113.04 ft²
