Complete the table below.

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

_______ | _________ | 616 cm |

###### Advertisements

#### Solution

Circumference, c = 616 cm

Now, c = 2πr .......(where 'r' is the radius)

⇒ 616 = `2xx22/7xx"r"`

⇒ r = `616xx1/2xx7/22`

⇒ r = 98

So, radius = 98 cm

Diameter, d = 2r = 2 × 98 = 196 cm

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

98 cm |
196 cm |
616 cm |
