- the difference between outside and inside surface of cylindrical metallic pipe 14 cm long is 44 square cm .if pipe is made of 99 cubic cm of metal, find the outer and inner radii of the pipe use pi as 44/7 Asked by:
**ansh** - Smita Kalra Curved surface area of the outer cylinder – Curved surface area of the inner cylinder = 44 cm2 2 * pi * (R - r) * 14 = 44 R - r = 1/2 ... (1) Volume of the metal in the pipe = 99 cm3 pi * (R^2 - r^2) * 14 = 99 From this you will get R + r = 9/2 ... (2) Adding (1) and (2), R = 5/2 Using any of these equations, you will get r = 2 Thus, the inner and outer radius of the pipe are 2 cm and 5/ 2 cm respectively.
