The ratio between the radius of the base and the height jof a cylinder is 2 : 3. Find the total surface area of the cylinder, if its volume is 1617 cm3.
Given,
Ratio between radius and height of a cylinder = 2:3
= 
= 
Volume of cylinder = 1617 cm3
= 
= 
= 
= 
Radius = 7 cm
Height = 
∴ total surface area of cylinder = 
15
