Answer 1

Answer:

Radius (r1) of 1st circle 19 cm

Radius (r2) or 2nd circle = 9 cm

Let the radius of 3rd circle be r.

Circumference of 1st circle = 2πr1 = 2π (19)

= 38TT

Circumference of 2nd circle = 2πr2 = 2TT

(9) = 18TT

Circumference of 3rd circle = 2πr

Given that,

Circumference of 3rd circle =

Circumference of 1st circle + Circumference of 2nd circle

2TT = 38T + 18 = 561

Therefore, the radius of the circle which has circumference equal to the sum of the circumference of the given two circles is 28 cm.
