Question

the circumference of the base of cylinder is 44 cm and its height is 7 cm find the volume of the cylinder and lateral surface area​

Answer 1

given circumference of the base of the cylinder = 44cm

therefore 2πr = 44cm (since base of a cylinder is circular)

--> 2 × 22/7 × r = 44cm

--> 44/7 × r = 44cm

--> r = 44 × 7/44

--> r = 7cm

given height of the cylinder = 7cm

volume of the cylinder = πr²h

= 22/7 × 7 × 7 × 7

= 22 × 49

= 1078cm³

lateral surface area of the cylinder = 2πrh

= 2 × 22/7 × 7 × 7

= 44 × 7

= 308cm²

Answer 2

Answer:

Step-by-step explanation:

We know circumference=2πr

44=2πr

r=7 cm.

Volume=πr^2h

=1078cm^3

Lateral surface area=2πRH

=308cm^2
