Step-by-step explanation:
for given cone:
h = 3 ft, r = 3 ft
Let l be the Slant height of cone.

Answer:
V = 54π cm³ ⇒ answer (C)
Step-by-step explanation:
∵ V = (πd²h)/8
∵ d = 6 cm
∵ h = 12 cm
∴ V = (π × 6² × 12) ÷ 8 = 54π cm³
The answer is B. The last too are both negative. So they are not true numbers.
