Answer:

Step-by-step explanation: The surface area formula for a cylinder is

A=2*π*r*h+2*π*r^2

This picture gives us the radius, which is 2cm, and it gives us the height which is 8cm.

All we have to do now is just plug in the two numbers.

A= 2πrh+2πr^2

A=2π*2*8 + 2π*4

A=4π*8+8π

A=32π+8π

A=40πcm

The answer is 40π cm then!

Please give this answer the brainliest or give me a heart, if you need additional help, please contact my friend and I on Instagram.
