Question

find the volume of cylinder whoose bace radius is 7cm and height 10cm

​

Answer 1

➼ Given :-

Radius of Cylinder = 7cm

Height of Cylinder = 10cm

➼ To Find :-

Volume of cylinder = ?

➼ Formula used here :-

Volume of cylinder = πr²h

➼ Solution Start :-

Volume of cylinder = πr²h

Volume of cylinder =$\frac{22}{7} \times 7 \times 7 \times 10 \\ \\ Volume \: of \: Cylinder = \frac{ 22}{ \cancel7} \times \cancel7 \times 7 \times 10 \\ \\ volume \: of \: cylinder \: = 22 \times 7 \times 10 \\ \\ volume \: of \: cylinder \: = 1540 \: {cm}^{2}$

Volume of cylinder = 1540 cm²
