Question

Find the surface area of the cylinder below. Use 3.14 for l~l. round your answer to the nearest tenth.

Answer 1

$\begin{gathered} \text{surface area=}2\pi r(r+h) \\ \pi=3.14 \\ r=32\text{ cm} \\ h=22\text{ cm} \end{gathered}$$\begin{gathered} \text{surface area=2}\times3.14\times32(32+22) \\ \text{surface area=}200.96(54) \\ \text{surafce area= }10851.84\text{ } \\ \text{surface area}=10851.8cm^2 \end{gathered}$
