Question 793325: A pillar in the shape of a cylinder has 21cm radius and 3m height.Find the curved surface area and the volume of the pillar. Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Volume = Pi*r^2 * h
Volume = Pi * 0.21^2 * 3
Volume = 0.42m^3
Curved Surface area
Circumference * height
Pi * 0.42 * 3
= 3.96 m^2
Hope this helps.
