Question

Find total surface area of a cylinder with height 1m and circumference of base is 176cm.

Answer 1

Answer:

Total Surface Area = Curved Surface Area + Lateral Surface Area

CSA = 2πrh = 176 x 100 = 17600 sqcm

LSA = 2 x πr^2 = 2πr x r = 176 x r

Now r = 2πr/2π = 176/2π = 176/2 x 7/22 = 28 cm

=> LSA = 176 x 28 = 4928 sqcm

=> TSA = 17600 + 4928 = 22528 sqcm
