Answer:
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 :

Where
r is radius of coin

Diameter, d = 2r
d = 2(26.57) cm
= 53.14 cm
Hence, this is the required solution.
