Question

the volume of the cylinder is 14 cm and its height is 12.5 cm .find the radius of its base.

Take pi =3.14

Answer 1

volume=14
3.14xr²x12.5=14
39.250x r²=14
r=0.5972335373

Answer 2

let the radius of its base is r(cm) and height 12.5 cm.


cylinder volume formula - πr^2h = πr^2 x 12.5 = 14 cm

                                               => r =  squre root[14/12.5 x π ]
                                                       = squre root[14/12.5 x 3.14 ]
                                                       = 0.59 cm = 59mm.
