Question
A solid cylinder has radius of base 14 cm and height 15
cm. 4 identical cylinders are cut from each base as shown in the given figure. Height of small cylinder is 5 cm. What is the total surface area (in cm2) of the remaining part?Solution
The part where we have cut the cylinder Top base is remove but lower base Crete, that means we can say no change in but C.S.A of 4 cylinder is add. 
Same case for lower base of original cylinder T.S.A of original cylinder + 8 × C.S.A 2 πR (R + h) + 8 × 2 πrh 2 × 22/7 × 14 × 29 + 8 × 2 × 22/7 × 7/2 × 5 2 × 22/7 (406 + 140) = 2 × 22/7 × 54 44 × 78 = 3432 cm2
