The circumference of the base of a cylindrical vessel is 132 cm and its height is 25 cm (use ?= 22/7) . Find the (i) Radius of the cylinder (ii) Volume of cylinder

Answer:

Let us consider

The radius of the cylinder = r

Height of the cylinder = h = 25 cm

Circumference of the cylinder = 132 cm

(i) Circumference of the cylinder = 2πr

132 = 2 × 3.14 × r

r = 132/6.29

r = 20.99 cm = 21 cm

(ii) Volume of the cylinder = πr2h

⇒ Volume of the cylinder = 3.14 × 21 × 21 × 25

⇒ Volume of the cylinder = 34,618.5 cm2
