Question

What is the surface area of this cylinder? A. 128 B. 256 C. 384 D. 1024

Answer 1

Surface area of a cylinder A= 2 $\pi$ r h+2$\pi$ r^2
A=2x3.14x8x16+(2x3.14x8x8)=803.84+401.92=1,205.76

Answer 2

Use the formula for the SA of cylinder to solve which is 2pir^2 + Pi r h.

Plug in the values for each variable and that will be the surface area.
