Joyce uses the formula S = 2pir(r+h) to find the surface area of a cylinder. Assuming she uses the correct values for r and h, will she get the correct volume? Why?

\(\color{red}S=2\pi r(r+h)\\S=2\times \pi r^2+2\pi r \times h\)

Yes it is right.

Twice the base area and

the outer surface as a product of circular circumference and height.
