Question

Find the surface area of this cylinder.Round to the nearest tenth.r = 3 cm|3 cmSA = [ ? ] cmEnter

Answer 1

Given:

Radius= r = 3 cm.

Height = h = 3 cm.

Surface area of cylinder is given by,

$\begin{gathered} SA=\text{ 2}\pi rh+2\pi\times r^2 \\ =2\pi(3)(3)+2\pi(3)^2 \\ =18\pi+18\pi \\ =36\pi \\ =113.1 \end{gathered}$

Answer: Surface area is 113.1 cm².
