Answer 1

||✪✪ QUESTION ✪✪||

Find the volume of a cylinder whose height is 20 cm and radius of base is 28 cm ?

|| ✰✰ ANSWER ✰✰ ||

Given That :-

→ Height of cylinder = 20cm.

→ Radius of base = 28cm.

we know That,

→ Volume of Cylinder = π * r² * h

Putting values we get :-

→ Volume = (22/7) * (28)² * 20

→ Volume = 22 * 4 * 28 * 20

→ Volume = 88 * 560

→ Volume = 49280cm³.

Hence, Volume of cone will be 49280cm³.

__________________________

Cylinder :-

→ Curved Surface Area = 2πrh

→ Total Surface Area = 2πr(h + r) .

→ Area of Both Base = 2πr².
