Question

Find the volume of cylinder, the diameter of whose base is 7 cm and height being 60 cm. Also, find the capacity of the cylinder in litres.

Answer 1

Given,

Diameter of base = 7 cm

Radius of base = \(\frac{7}{2}\) cm

Height of cylinder = 60 cm

∴ Volume of cylinder = πr²h = \(\frac{22}{7}\) x \(\frac{7}{2}\) x \(\frac{7}{2}\) x 60 = 2310 cm³

Capacity of cylinder in litres = \(\frac{2310}{1000}\) = 2.31 litre
