Question

the circumference of the base of a cylinder is 88 cm and its height is 65 cm. find its lateral surface area​

Answer 1

Answer:

6952 cm²

Step-by-step explanation:

C = 2πr

But , C = 88cm (given)

Putting the values, we get :

2πr = 88cm

r = 88/2π = 88×7/2×22 = 14cm

Lateral surface area = 2πr(r+h)

= 2 π 14 (14+65)

=

$2 \times \frac{22}{7} \times 14 \: \times 79$

= 6952 cm²
