Radius (r)  Diameter (d) Circumference (c)
_______ _________ 616 cm

Solution

Circumference, c = 616 cm
Now, c = 2πr .......(where 'r' is the radius)
⇒ 616 = `2xx22/7xx"r"`
⇒ r = `616xx1/2xx7/22`
⇒ r = 98
So, radius = 98 cm
Diameter, d = 2r = 2 × 98 = 196 cm

Radius (r)  Diameter (d) Circumference (c)
 98 cm 196 cm 616 cm
