Question

find the volume of a right circular cylinder if circumference of base = 1.32 M and height =25CM

Answer 1

Hope it helps...............

Answer 2

hiii!!!

here's Ur answer...

given the circumference of the base is the right circular cylinder = 1.32m = 132cm

therefore 2πr = 132cm

==> 2 × 22/7 × r = 132cm

==> 44/7 × r = 132cm

==> r = 132/1 × 7/44

==> r = 3 × 7

==> r = 21cm

verification :-

circumference of the base of the right circular cylinder = 2πr

= 2 × 22/7 × 21

= 44 × 3

= 132cm

hence verified..

thus the radius of the right circular cylinder is 21cm.

given the height of the cylinder is 25cm.

now, volume of the cylinder = πr²h

= 22/7 × 21 × 21 × 25

= 22 × 3 × 21 × 25

= 34650cm³

hope this helps..!!
