Complete the table below.

Radius (r) | Diameter (d) | Circumference (c) |

7 cm | ______ |
_______ |

###### Advertisements

#### Solution

Radius, r = 7 cm

Diameter, d = 2r = 2 × 7 = 14 cm

∴ Circumference, c = πd

= `22/7xx14`

= 22 × 2

= 44 cm

Radius (r) | Diameter (d) | Circumference (c) |

7 cm | 14 cm |
44 cm |
