Answer 2

Hello!

To find the surface area of a cylinder you use the equation

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

SA is surface area
r is radius
h is height

Put in the values you know

$SA = 2 \pi 9 * 19 + 2 \pi 9^{2}$

Square the number

$SA = 2 \pi 9 * 19 + 2 \pi 81$

Multiply the 9, 19 and 2

$SA = 342 \pi + 2 \pi 81$

Multiply the 2 and 81

$SA = 342 \pi + 162 \pi$

Add

$SA = 504 \pi$

The answer is $504 \pi$

Hope this helps!
