Question

SA = 2rr2 + 2nrh (Use 3.14 for a Find the surface area of a cylinder that has a base radius of 2 feet and a height of 14 feet. square feet Do NOT round your answer

Answer 1

Surface area is given as

`2\pi r^2+2\pi rh`
`\begin{gathered} r=2ft \\ h=14ft \\ \pi=3.14 \end{gathered}`

Substitute the value into the formula above

`\begin{gathered} SA=2*3.14*2^2+2*3.14*2*14 \\ =\text{ 25.12+175.84} \\ =200.96 \end{gathered}`

SA = 200.96 square feet(ft²)
