The difference between the circumference and the radius of a circle is 111 cm. What is it radius?
​

I don't know follow the hint below i guess

Step-by-step explanation:

The circumference is pi x diameter. Double the radius to get the diameter.

21 cm

Step-by-step explanation: Given

Circumference of a circle with radius (r)-radius (r)=111 cm

(2πr−r)=111

r(2π−1)=111

r(44/7−1)=111

r[(44/7−7)/7]=111

​∴r=111×7/37=3×7=21cm

∴ radius is 21 cm.

Hope this helps!! :)

.25
