Question

Find the surface area of a cylinder with a base radius of 6 ft and a height of 9 ft.Use the value 3.14 for n, and do not do any rounding.Be sure to include the correct unit.

Answer 1

The surface area of the cylinder can be found below

$\text{surface area=}2\pi r(r+h)$

h = 9 ft

r = 6 ft

Therefore,

$\begin{gathered} \text{surface area=2}\times3.14\times6(6+9) \\ \text{surface area=}37.68(15) \\ \text{surface area=}565.2ft^2 \end{gathered}$
