the surface area of a cylinder is 1000 pi square centimeters.
the radius of the cylinder is four times the height.
what is the height of the cylinder.
:
LET x = the height
"radius is 4 time the height" therefore
4x = the radius
:
S.A. = +
so we have
+ =
divide equation by 2pi
= 500
= 500
= 500
divide both sides by 20
= 25
x =
x = 5 is the height
