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

$\begin{gathered} SA=2\times3.14\times2^2+2\times3.14\times2\times14 \\ =\text{ 25.12+175.84} \\ =200.96 \end{gathered}$

SA = 200.96 square feet(ft²)
