Sagot :
easy peasy here we go..
so first circumference = 2π R
now it is given that circumference - 30 cm = Diameter;
Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}
now solving equations:
2πR -2R = 30
πR - R = 15
R ( π - 1 ) = 15
R ( 22/7 - 1) = 15
R ( 15/7 ) = 15
R = 15 x 7 / 15
R = 7 cm

Answer:
7.01 cm
Step-by-step explanation:
Circumference = 2πr
=> d + 30 = 2πr
=> 2r + 30 = 2πr
=> 2r(π - 1) = 30
=> 2.14r = 15
=> r = 15/2.14
=> r = 7.01 cm
