Answer:

28cm

Explanation:

The circumference of the circle is equal to the perimeter of the rectangle which is

2(L+B)

2(52+36)

2(88)

176cm

using the formula for circumference of a circle

C=2πr

176=2×22/7×r

176=44r/7

cross multiply

44r=176×7

44r=1232

divide both side by the co-efficient of X which is 44

44r/44=1232/44

r=28cm

I hope this helped
