a cylinder has a height of 1 foot and a radius of 2 feet,
what is the approximate surface area.
:
The surface area of the side would be the circumference * height
The surface area of the ends, the areas of the top and bottom
so we have:
S.A. = 2%2Api%2Ar%5E2 + 2%2Api%2Ar%2Ah
:
S.A. = 2%2Api%2A2%5E2 + 2%2Api%2A2%2A1
