According to question
Circumference - Diameter = 30
=> pi *d - d = 30
=> d ( pi - 1) = 30
=> d ( 22/7 - 1) = 30
=> d (22-7) / 7 = 30
=> d * 15 = 30 * 7
=> d = 30 * 7 / 15
=> d = 14 cm
Radius of circle = 14 / 2
= 7 cm
Circumference - Diameter = 30
=> pi *d - d = 30
=> d ( pi - 1) = 30
=> d ( 22/7 - 1) = 30
=> d (22-7) / 7 = 30
=> d * 15 = 30 * 7
=> d = 30 * 7 / 15
=> d = 14 cm
Radius of circle = 14 / 2
= 7 cm
thanks brother
what is pi.......
pi = 22/7
or 3.14
π = 31415926535
