The circumference of base of a cylinder is 12cm and hieght is 11m then

1.	The circumference of base of a cylinder is 12cm and hieght is 11m then the volume of cylinder is
Answer» ★ Circumference = 12cm = 0.12 But, Circumference = 2πr => 2πr = 0.12 m R = 0.12/2π ★ HEIGHT (h) = 11m Now, Volume of CYLINDER = πr^2 × h = π (0.12/2π)^2 × 11 = {(0.12)^2}/4π × 11 = 0.0144/4π × 11 = 0.0036/3.14 × 11 = 0.0012 × 11 = 0.013 m^3 Hence, the volume of the cylinder is 0.013m^3.

The circumference of base of a cylinder is 12cm and hieght is 11m then the volume of cylinder is

Answer»

★ Circumference = 12cm = 0.12

But, Circumference = 2πr

=> 2πr = 0.12 m

R = 0.12/2π

★ HEIGHT (h) = 11m

Now, Volume of CYLINDER = πr^2 × h

= π (0.12/2π)^2 × 11

= {(0.12)^2}/4π × 11

= 0.0144/4π × 11

= 0.0036/3.14 × 11

= 0.0012 × 11

= 0.013 m^3

Hence, the volume of the cylinder is 0.013m^3.
