Question

Find the volume of a cylinder whose

(i) r = 3.5 cm, h = 40 cm

(ii) r = 2.8 m, h = 15 m

Answer 1

(i) Given,

r = 3.5 cm

h = 40 cm

Volume = πr²h = \(\frac{22}{7}\) x 3.5 x 3.5 x 40 = 1540 cm³

(ii) Given,

r = 2.8 m

h =15 m

Volume of cylinder = πr²h = \(\frac{22}{7}\) x 2.8 x 2.8 x 15 = 369.6 m³
