Question

the circumference of the base of the cylinder is 176 cm and it's height is 65 cm .Find the volume of the cylinder and it's lateral surface area​

Answer 1

Circumference = 2πr

2πr = 176 cm (eq1)

r = 176×7/22×2

r = 8×7/2 = 4×7

r = 28 cm

Volume = πr²h

V = 22/7 × 28 × 28 × 65

V = 22×4×28×65

V = 160,160 cm³

LSA = 2πrh

From eq1

2πr = 176 cm

2πrh = 176 × 65 = 11,440 cm²
