Question
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 |
