You put it in a ratio so it's 24/30 = x/4 so the answer is 3.2 feet
Volume of a sphere = (4/3)πr³ π ≈ 3.14, r = 9
Volume, V = (4/3)πr³
V ≈ (4/3)*3.14*9³
V ≈ (4/3)*3.14*9*9*9 Use calculator
V ≈ 3052.08
Option A.
Hope this helps.
I'm sorry hun, i suck at math. If i knew how i would help you. Have you tried looking it up?
Answer:
I think so, but maybe if the schools are different they change.
