Question

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

Answer 1

Step-by-step explanation:

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

$\therefore \: r = \frac{d}{2} \\ \\ \therefore \: r = \frac{10}{2} \\ \\ \therefore \: r = 5 \: kilometers.$

Hence radius of the circle is 5 kilometers.
