Question

A construction company was contracted to build a cylindrical storage tank with a diameter of 48 feet and height of 25 feet. Just before construction was to begin, it was learned that a new law allows tanks to be a maximum of 9 feet in height.
If the tank is redesigned to meet the law, but has the same volume, what is its new diameter?

Answer 1

volume = \[\Pi r ^{2} \times h\]
as both volume same so
\[\Pi 24^{2}\times25 = \Pi r ^{2}\times9\]
r=40

Answer 2

thank you that helped !!!

Answer 3

welcome :)
