Question

The circumference of base of cylinder is 198 cm and height is 12 cm.Find the volume of the cylinder.​

Answer 1

Answer:

37422

Step-by-step explanation:

cirumference of base=198cm

2πr=198cm

r=198X1/2X7/22

r=63/2cm

volume of cylinder=πr2h

=22/7X63/2X63/2X12

=99X378

=37422cm2

Answer 2

Circumference of base of cylinder = 198 cm

Height of cylinder = 12cm

We know that,

Circumference of a circle = 2πr

198 = 2*22*r

7

198*7

2*22

= 31.5 = radius

We know that,

Volume of a cylinder = πr²h

= 22 * 31.5*31.5*12

7

= 37,422cm²
