Question

find the volume of the cylinder if the circumference of the cylinder is 132cm and height is 25cm?​

Answer 1

Circumference of base =
[tex]2\pi r[/te]
132 =2*22/7r
R=132 *7/2*22
R=21
Volume =22/7*21*21*25
=34650

Answer 2

answer is:

circumference of circle=2πr

=132cm=2×22/7×r

=132cm×7/22×2=r

=r=21cm

now,volume of cylinder=πr×r×h

=22/7×21cm×21cm×25cm

=34650cm^3

hence,34650cm^3is the right answer.
