Question

Two diameters is 200 mm find the radius of the circle in centimetre. I need formula and step by step

Answer 1

radius = d/2
= 200 / 2
= 100mm
1mm = 10cm
therefore 100mm = 1000cm

Answer 2

HERE IS YOUR ANSWER :

Let the diameter be d and radius be r.

2d = 200 mm.

d = 100 mm.

d = 50 mm = 5 cm.

Therefore, r = d/2 = 5/2 cm

-----》RADIUS = 2.5cm
