You can put this solution on YOUR website! The volume of a cylinder of height 8 cm is 1232 cm3. Find its curved surface area and the total surface area.
***
let r=radius of cylinder
let A =Area of one end=πr^2
h=height=8
v=volume of cylinder=1232
A*h=volume
πr^2*8=1232
πr^2=1232/8=154 cm^2(area of one end)
r=√(154/π)≈7
Curved surface area=circumference*height=2πr*8=351.86 cm
Total surface area=2*154+351.86=659.86 cm^2
