Answer:
2.5
Explanation:
radius = Diameter ÷ 2
We plug the diameter value that we know
radius = 5 ÷ 2
Then Solve
5 ÷ 2 = 2.5
Done!
Remember diameter divided by two = the radius
Why? Because one radius is equivalent to 1 half. So we need two halves to form one full.
The diameter is the size of the full length which is why it is divided by two in order to form two halves!
