given: circumference= diameter+180
2πr= 2r+180
2×22/7×r= 2r+180
44r/7 -2r =180
30r/7 =180
r= 180×7/30
r= 42 cm
here is the answer

Answer:
Step-by-step explanation:
Let the circumference be x
Then,
Diameter=180+x
So
Circumference=πd
22/7×x+180=x
15x=1260
X=84cm
Therefore circumference=180+x
=264cm
Radius=84/2=24
