Radius (r)  Diameter (d) Circumference (c)
_______ _________ 72.6 cm

Solution

Circumference, c = 72.6 cm
Now, c = 2πr .........(where 'r' is the radius)
⇒ 72.6 = `2xx22/7xx"r"`
⇒ r = `72.6xx1/2xx7/22`
⇒ r = 11.55
So, radius = 11.55 cm
Diameter, d = 2r = 2 × 11.55 = 23.1 cm

Radius (r)  Diameter (d) Circumference (c)
11.55 cm  23.1 cm 72.6 cm
  Is there an error in this question or solution?
