Question

Find the volume of cylinder whose diemerter is 14cm and height is 20cm

Answer 1

Step-by-step explanation:

given

radius=d/2

=14/2

radius=7

height=20cm

We know that,

Volume of cylinder= πr^2h

=22/7x(7)^2x20

=22x7x20

=3,080cm^3

Answer 2

Step-by-step explanation:

volume of cylender=pier²h

1. radius=14/2=7
2. height=20cm

area of cylender=pier²h

22/7*7*20=440cm²
