Question

The diameter of a circle is 10 kilometers. What is the circle's radius?
d=10 km

Answer 1

Explanation:

Let diameter of the circle be d and radius be r.

`\therefore \: r = (d)/(2) \\ \\ \therefore \: r = (10)/(2) \\ \\ \therefore \: r = 5 \: kilometers.`

Hence radius of the circle is 5 kilometers.
