Question

the radius of circular base of a cylinder is 14 cm and height is 20cm find the volume of cylinder​

Answer 1

Question:

the radius of circular base of a cylinder is 14 cm and height is 20cm find the volume of cylinder

Answer:

Given:

the radius of circular base of a cylinder is 14 cm

height is 20 cm

To find:

find the volume of cylinder

Solution:

Radius of the cylinder = 14/2 = 7 cm

We know that$\boxed{\bf{\red{V=πr^{2}h}}}$

Where,

V = volume of the cylinder

r = radius of the cylinder

h = height of the cylinder

π = 22/7

Therefore,

Volume of the cylinder

$\sf{\implies πr^{2}h}$

$\sf{\implies \dfrac{22}{7}×7×7×20\:cm^{3}}$

$\sf{\implies 3080\:cm^{3}}$

Hence, volume of the cylinder is 12320 cm³
