The difference between the circumference and the diameter is 30cm . Find the radius of the circle |
|
Answer» circumference=2pirdiameter=2r2 pi r - 2r = 302r (pi - 1) = 30r = 15 / 22/7 -\xa01 = 15 x 7 / 15 = 7 cm 30 cm If u take radius as x then diameter will be 2x.So 2x-x=30. So x is 30Radius is 30 cm |
