The ratio between the curved surface area dna the total surface area of a right circular cylinder is 1 : 2. Find the volume of the cylinder, if its total surface area os 616 cm2.
Given,
Total surface area of cylinder = 616 cm2
Ratio between curved surface area and total surface area of cylinder = 1 : 2
= 
= 
= 
= 
= 
= 
= 
= 
Radius = 7 cm = height
∴ Volume of cylinder =
