Diameter of a Circle</h2>
There are multiple strategies we can use to find the diameter of a circle. For this question, we must calculate the length of the radius first and multiply by 2 to find the diameter.
<h2>Solving the Question</h2>
We're given the centre and a point on the circumference:
.
Find the distance between them using the distance equation:

Plug in the given points:

Therefore, the radius of the circle is 10 units.
Multiply the radius by 2 to find the length of the diameter:
10 × 2
= 20
Therefore, the length of the diameter is 20 units.
<h2>Answer</h2>
