Question 1098435: The formula for the surface area of a cylinder is S = 2(pi)r^2 + 2(pi)rh. The surface area of a cylinder is 112(pi) square inches and the radius is 4 inches. What is the height of the cylinder? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The formula for the surface area of a cylinder is S = 2(pi)r^2 + 2(pi)rh. The surface area of a cylinder is 112pi square inches and the radius is 4 inches. What is the height of the cylinder?
------------
S = 2pi*r^2 + 2pi*r*h
--------
Putting parentheses around pi is a waste of time.
============
S = 2pi*r^2 + 2pi*r*h = 112pi
r = 4
Sub 4 for r, solve for h
