Find the missing values in the following table for the circles with radius (r), diameter (d) and Circumference (C).

radius (r) diameter (d) Circumference (C)
15 cm

Solution

Given: radius r = 15 cm

∴ diameter d = 2 × 15 = 30 cm

Circumference C = πd units

= `22/7 xx 30`

= `660/7`

= 94.28 cm

Tabulating the results

radius (r) diameter (d) Circumference (C)
15 cm 30 cm 94.28 cm
  Is there an error in this question or solution?
