There are many cylinders with volume 452 cm . Let r represent the radius of these cylinders V and h represent the height. This means the formula of the volume , in cubic centimeters, of V = πr h2
these cylinders is and the equation for the surface area, in square centimeters, is
S = 2πr2 + 2πrh
.
3
Write an equation for S as a function of r when the volume of the cylinder is 452 cm
