Question

In a cone, height=15cm
volume=1570 cm.sq
find the radius​

Answer 1

Here is your answer..

==================

Given :- volume = 1570 sq cm

height = 15 cm

Formula :- volume = 1/3πr^2 h

1570 =1/3×3.14×r^2×15

1570×3 = 1×3.14×r^2×15

4710 = 47.1×r^2

4710/47.1= r^2

47100/471 = r^2.......

[multiplying both sides with 10...]

100 = r^2

10=r

hence.., Radius of cone is 10 cm....
