Question

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

Answer 1

Answer:

Radius, r = 26.57 cm and diameter = 53.14 cm

Step-by-step 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

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{167}{2\pi}\\\\r=26.57\ cm$

Diameter, d = 2r

d = 2(26.57) cm

= 53.14 cm

Hence, this is the required solution.
