The difference between the outer and inner curved surface areas of a hollow right circular cylinder, 14cm long, is 88cm2. If the volune of metal used in making the cylinder is 176cm3, find the outer and inner diameters of the cylinder
We have to find the inner and the outer radius of a hollow cylinder whose height(h) = 14 cm
So,
Outer curved surface area - Inner curved surface area = 88
.......(1)
Also we have,
Volume of outer part - Volume of inner part = 176
.......(2)
Using (1) and (2), we get,
