9- -16 i think lemme do the next ones
A common denominator is 12
Answer: the answer is 7.
Step-by-step explanation:
you take 12, divide it by 3 to get 4, then you add 3 to get 7.
V = r² π h + 1/2 · 4/3 r³ π
V = 6² · 22/7 · 198 + 4/6 · 6³ · 22/7
V = 36 · 22 · 24 + 144 · 22/7 = 19,008 + 452.57 = 19,460.57 ≈ 19,461 ft³
Answer: B ) 19,461 ft³
