Question
A cylindrical metal drum of height 125cm has a capacity of 693 l. Calculate the diameter of the drum?
Answers
First, know the volume of the drum: 693L = 0.693m3
Second, divide by the height (1.25m) to obtain the cross-sectional area: 0.693/1.25 = 0.5544m2
Finally, calculate the diameter rearranging the formula area = pi * diameter2 / 4
diameter = square-root (4 * area / pi)
diameter = 0.84m
