Question

The circumference of a coin is 167 cm. What is the radius? What is the diameter?

Answer 1

Radius, r = 26.57 cm and diameter = 53.14 cm

Explanation:

Given that,

The circumference of a coin, C = 167 cm

We need to find the radius and the diameter of the coin.

The formula for the circumference of a circle is given by :

`C=2\pi r`

Where

r is radius of coin

`r=(C)/(2\pi)\\\\r=(167)/(2\pi)\\\\r=26.57\ cm`

Diameter, d = 2r

d = 2(26.57) cm

= 53.14 cm

Hence, this is the required solution.
