The answer to the question is d.
Answer:

Step-by-step explanation:

we can use the distributive property and get

and we can add like terms

and know we divide both sides by 16.5

and doing the dvision we get that

Given:
V = 5x² + 15x + 2, the volume
h = 5x, the height
Let A = the area of the base.
Because V = Ah, therefore
A*(5x) = 5x² + 15x + 2

Answer:
V = 4/3πr^3V = 4/3 (π) (6.5)^3
V = 366.1666π (6 repeat)
answer is 366.16 π (3rd choice)
