Question

The volume of cylinder if radius is 7 cm and height is 5cm is​

Answer 1

Answer:

The volume of the cylinder is 770 cm³.

Step-by-step-explanation:

We have given that,

For a cylinder,

• Radius ( r ) = 7 cm
• Height ( h ) = 5 cm

We have to find the volume of cylinder.

We know that,

$\displaystyle{\pink{\sf\:Volume\:of\:cylinder\:=\:\pi\:r^2\:h}}$

$\displaystyle{\implies\sf\:Volume\:of\:cylinder\:=\:\dfrac{22}{7}\:\times\:7^2\:\times\:5}$

$\displaystyle{\implies\sf\:Volume\:of\:cylinder\:=\:\dfrac{22}{\cancel{7}}\:\times\:\cancel{7}\:\times\:7\:\times\:5}$

$\displaystyle{\implies\sf\:Volume\:of\:cylinder\:=\:22\:\times\:7\:\times\:5}$

$\displaystyle{\implies\sf\:Volume\:of\:cylinder\:=\:110\:\times\:7}$

$\displaystyle{\implies\underline{\boxed{\red{\sf\:Volume\:of\:cylinder\:=\:770\:cm^3}}}}$

∴ The volume of the cylinder is 770 cm³.
