Answer:

A, B and C be the circumference of circle A, B and C respectively.

A = 132cm

since the sum of circumference B and C is equal to circumference A, thus,

B + C = A

B + C = 132 ----------- eqn(1)

radius of B, rB = 14

B = 2πrB

= 2 x π x 14

= 28π

eqn(1) becomes:

28π + C = 132

subtract 28π from both sides

C = 132 - 28π

C = 44.0354

Also, C = 2πrc

44.0354 = 2πrc

divide both sides by 2π

rc = 44.0354/2π

rc = 7cm

Therefore, the radius of circumference C is 7cm
