Question

A circle has a radius of 7.5 cm what is the diameter?

Answer 1

If we have a circle that has a radius of 7.5 cm, that would imply that we would need to use the formula 2r = d.

This formula says that if we take the radius of our circle and multiply it by 2, we end up with the diameter of our circle.

So 2 × 7.5 cm gives us 15 cm.

So the diameter of this circle is 15 cm.

Answer 2

Answer:

15

Step-by-step explanation:

Radius times 2 is the diameter!
