Given: Circumference of the base of cylinder = 132 cm and height (h) = 25 cm.

To find: Volume of the cylinder 

i. Circumference of base of cylinder = 2πr

ii. Volume of the cylinder = πr2h

= \(\cfrac{22}{7}\)x 21 x 21 x 25

= 22 x 3 x 21 x 25 

= 34650 cc

∴ The volume of the cylinder is 34650 cc.

Let 'r' be the radius of the cylinder. Circumference=132cm

2πr=132cm

2×722​×r=132cm

∴r=2×22132cm×7​

∴r=21cm

Volume of a cylinder==722​×(21)2×25

=> 722​×21×21×25

=> 34,650cm3.laugh
