If the difference between the circumference and diameter of a circle is 60 cm, then the radious of the circle is .

If the difference between the circumference and diameter of a circle is 60 cm, then the radious of the circle is . Correct Answer 7 cm

ATQ, 2λr - 2r = 60⇒2r (λ - 1) = 60⇒r = 602(λ - 1) = 30227 - 1 = 3022 - 77 = 3015×7.'. r  = 14 cm
