Cistern A and Cistern B both have a height of 10 feet. Cistern A has a radius of 10 feet and Cistern B has a radius of 20 feet. Does Cistern B hold twice as much water? Why or why not?
I solved the first part like this. I'm right?
now I have doubts in part two. Is it because of the ratio of 1 to 4?
Thanks!!
V= VA = A*h
V= pi*r^2*10
V = 3,140 ft^3
VB = A*h
V= pi*r^2*h
V= 12,560 ft^3
