Question

A geyser is cylindrical in shape whose diameter is 28 cm and height 1.5 m. Neglecting the thickness of its walls, calculate its capacity.

Answer 1

Given:

Diameter = 28 cm ⟹ radius r =14r = 14r =14 cm

Height = 1.5 m = 150 cm

π = `22/7`

Capacity of the geyser

Volume of a cylinder: V = πr²h

Substituting the values: V = `22/7 xx 14^2 xx 150`

= `22/7 xx 196 xx 150`

= 92400 cm³
