Find the volume of a cylinder, if the diameter (d) of its base and its altitude (h) are:

(i) d = 21 cm, h = 10cm

(ii)d = 7 m, h = 24 m

Answer:

(i) Given, d = 21cm

r = d/2 = 21/2cm h = 10 cm.

By using the formula,

Volume of cylinder = πr2h

= 22/7 × 21/2 × 21/2 × 10

= 3465 cm3

(ii) Given,

d = 7 m

r = d/2 = 7/2m h = 24 m

By using the formula,

Volume of cylinder = πr2h

= 22/7 × 7/2 × 7/2 × 24

= 924 m3
