Question

Calculate the volume of a cylinder of radius 5 cm and height 10 cm.

Answer 1

Given:-

Radius of the cylinder = $5cm=\frac{5}{100}m=\frac{1}{20}m$

Height of the cylinder = $10cm=\frac{10}{100}m=\frac{1}{10}m$

Finding volume of the cylinder:-

Volume of the cylinder $={\mathrm{\pi r}}^2\mathrm{h}=(\frac{22}{7}\times \frac{1}{20}\times \frac{1}{20}\times \frac{1}{10}){\mathrm{m}}^3=0.000785{\mathrm{m}}^3$

Hence volume of cylinder is 0.000785 m³.
