Question

Find the height of the cylinder whose volume is 1.54 m³ and diameter of the base is 140 cm?

Answer 1

We have, volume of the cylinder

= 1.54 m³

= 1.54 × 106 cm³

Diameter = 140 cm, Radius= 140 ÷ 2 = 70 cm

∵ volume of the cylinder = πr²h

= 1.54 × 106 = `22/7 xx (70)^2 xx h`

= `(1.54xx10^6xx7)/(22xx70xx70) xx h`

= 100 cm = h

∴ The height of the cylinder is 100 cm.
