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
