Question

The volume of a cylinder is 2521 cu cm and it's height is 12.5 cm find the radius of its base ( take pai =3.14)

Answer 1

hi! here is your answer! ! !

Volume of cylinder=2521cu.cm.

height=12.5cm

we know that,

volume of cylinder=πr^2h

2521=3.14×r^2×12.5
2521=39.25×r^2
r^2=2521/39.25
r^2=252100/3925
r^2=64
(by taking square root to both sides.)

r=8cm

Therefore,
The radius of the cylinder is 8cm.

hope this helps ! ! ! #
