Question

Aiden works at a lab with a huge circular particle accelerator. It has a diameter of 8 kilometers. What is the accelerator's radius?

Answer 1

Hey mate!

The radius is 4km

Here's how:-

Diameter is 2 times the radius.

That means, the radius is half of the diameter.

So, radius equals 8 divided by 2.

Radius is 4cm.

Hope it helps!

Answer 2

Explanation:

Diameter = 2x Radius

Radius = 1/2 Diameter

`= (1)/(2) * 8 \\ = 4km`
