The diameter and height of a cylinder are 1.4 m and 1 m respectively. Find the volume of this cylinders.

Answer 1

Given, h=1, d=1.4 =》r=d/2=》》r=0.7
formula is πr^2h
=》(22*0.7*0.7)/7 m^3
=》0.49*22/7 m^3
=》10.78/7 m^3
=》1.54 m^3

Answer 2

Given diameter = 1.4 m.

Given, radius r = d/2 = 0.7 m.

Given, height h = 1 m.

Now,

We know that volume of the cylinder = πr^2h

⇒ (22/7) * (0.7)^2 * (1)

⇒ (22/7) * 0.49 * 1

⇒ 22 * 0.07

⇒ 1.54 .

Therefore, the volume of the cylinder = 1.54 m^3.

Hope it helps!
