How tall is a 628 cubiccentemeter cylinder that has a diameter of 10 cetemeters?
Perimeter,area and volume

formula for volume of cylinder: V = πr2h
substitute 628 to V: πr2h = 628
we know r = 5 cm because 2r = d = 10 cm
π(52)h = 628
let's use the approximation of pi which is 3.14
h = 628 / (25 * 3.14)
therefore, h = 8 cm.
