Answer:

Circumference =2πr

given = circumference of a circle is equal to the radius of 2 circle of diameter 36 and 20 cm

r1= 36/2 = 18 CM ................( 1)

r2 = 20/2 = 10 CM................. (2)

let the radius of the circle is R

Circumference = 2πr1+ 2πr2

= 2*22/7*18 + 2*22/7 *10

= cancel 2π both the sides

R = 18 + 10 cm

R = 28 CM

The radius of the circle is 28 cm
