Question

Find the volume of this cylinder. Use 3 for A.5 ftV = 7r2h=12 ftV V [?]ft

Answer 1

We're going to find the volume of the cylinder using the following equation:

$V=\pi\cdot r^2\cdot h$

Since the radius measures 5 ft, the height measures 12 ft and the problem tells us that we should take pi as 3, we could replace:

$\begin{gathered} V\approx3\cdot(5ft)^2\cdot12ft \\ V\approx3\cdot25ft^2\cdot12ft \\ V\approx900ft^3 \end{gathered}$

Therefore, the volume is approximately 900ft3.
