Question

Help find the volume of the cylinder with area and base given!

Answer 1

The volume of a cylinder is;

`V=\pi r^2h`

where r is the radius

radius = diameter/2

h is the height

here, the height is a = 1 cm

radius = 21/2 cm

Hence, the volume is

`\begin{gathered} V=\pi*((21)/(2))^2*1 \\ \\ \Rightarrow V=(22)/(7)*(21)/(2)*(21)/(2)*1 \\ \\ \Rightarrow V=346.5\text{ cm}^3 \end{gathered}`
