Please help Me!! D: There is a pi in there in 972.
2 answers:
V = 4/3 pi r^3
r^3 = 3V / 4pi
r^3 = (3 * 972pi) /(4pi)
r^3 = 729
r = 9
Answer
B. 9 inches
V = 4/3 π r³
Given that v = 972π
972π = 4/3 π r³
\\Multiply by 3 on both sides
2916π = 4 π r³
\\ Divide by 4π on both sides
729 = r³
\\cube root both sides
∛729 = r
9 = r
Answer: r = 9 inches
