Question

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

Answer 1

★ 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.
