Question

What is the surface area of the cylinder in terms of pi? The diagram is not drawn to scale.A) 288B) 360C) 72D) 162thank you ! :)

Answer 1

ANSWER :

B. 360π in^2

EXPLANATION :

Recall the surface area of a cylinder :

$SA=2\pi r^2+2\pi rh$

From the problem, the radius is 6 inches and the height is 24 inches.

Using the formula above :

$\begin{gathered} SA=2\pi(6)^2+2\pi(6)(24) \\ =72\pi+288\pi \\ =360\pi\text{ }in^2 \end{gathered}$
