Question

Volume of a cylinder?

Answer 1

A cylinder has a base, and a height,



The volume of the cylinder is the area of the bases time the height

Answer 2

When the base is a circle, use
the area of a circle \(A_\text{circle} = π r^2\),
where \(r\) is the radius of the circle

Answer 3

\[V_\text{cylinder}=b\times h\\
~\\
V_\text{circular cylinder}=A_\text{circle}\times h\\
\qquad\qquad\qquad=\pi r^2h\]
