Question

A cylinder has a base area of 2.5 ft2 and a height of 7 ft.

What is the volume of the cylinder?

_________ ft3

Answer 1

$V=\pi r^2 h\\V=(A)h\\V=(2.5)(7)\\V=17.5$

17.5 cubic feet.

Answer 2

$The\ cylinder\ volume:V=Bh\\\\B-a\ base\ area;\ h-height\ of\ cylinder\\---------------------\\\\B=2.5\ ft^2;\ h=7\ ft\\\\therefore\\\\\boxed{V=2.5\ ft^2\cdot7\ ft=\boxed{17.5\ ft^3}}$
