Question

If the circumference of a circle is 198cm, find its radius.
​

Answer 1

Answer:

circumference of circle=2πr

198=2×π×r

transposing 2 from LHS to RHS

198/2=πr

99=πr

putting value of. π(pie)

We get,

99=22/7×r

transposing 22/7 to LHS

99×7/22=r

31.5=r

hope it will hepl uh.

Answer 2

Answer:

31.5cm

Step-by-step explanation:

the circumference formula of circle is 2πr

given circumference is 198

We need to equate both ,then we get radius

2πr=198,

r=31.5cm
