Question

Circumference of a circle exceeds its diameter by 180cm find its radius

Answer 1

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 2

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
