Answer :

In a circle, the sum of two diameters = 200 mm

Let diameter be d and radius be r of a circle.


d + d = 200 mm


2d = 200 mm


d = 100 mm


We know that Diameter = 2(Radius).


100 = 2r


r = 100 ÷ 2


r = 50 mm


We know that 1 cm = 10 mm.


r = 50 ÷ 10 = 5 cm


The radius of the circle is 5 cm.
