Question

Find the surface area of the cylinder

Answer 1

Lateral surface area = \(2\pi r h\)
Area of two ends = \(2\pi r^2 \)
Total surface area = \(2\pi r (r+h)\)

Answer 2

The radius is 6 feet and the height is 20 feet. How do I plug in the numbers into the problem?

Answer 3

first do the 2*pi*r*h
but replace the letters with the numbers, and multiply it out
that is the lateral area
then do the area of the two ends (circles)
both are pi * r*r

Answer 4

in case it's not obvious, r is for the radius, and h is for the height.
