Question

find the volume of cylinder whose diameter is 12 cm and height is 20 cm​

Answer 1

the answer is in the picture.

Answer 2

Answer :

• Volume of cylinder is 2262 cm³

Given :

• Diameter = 12cm
• Height = 20cm

To find :

• Volume of cylinder

Solution :

Given,

• Diameter = 12cm

First we need to find radius,

As we know that,

• Radius = Diameter/2

》Radius = 12/2

》 Radius = 6cm

Hence , Radius is 6cm

As we know that,

• Volume of cylinder = πr²h

where , r is radius 6cm and h is height 20cm

》Volume of cylinder = πr²h

》22/7 × (6)² × 20

》22/7 × 6 × 6 × 20

》22/7 × 36 × 20

》 22/7 × 720

》2262 cm³

Hence, Volume of cylinder is 2262 cm³
