Complete the table below.

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

_______ | 28 cm | _________ |

###### Advertisements

#### Solution

Diameter, d = 28 cm

Radius, r = `"d"/2=28/2` = 14 cm

∴ Circumference, c = 2πr

= `2xx22/7xx14`

= 88 cm

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

14 cm |
28 cm | 88 cm |
