Question

Which circle has a radius that measures 10 units?

Answer 1

The answer is B) because if 20 is the diameter then 10 would be the radius.

Answer 2

The 2nd circle (circle F)

Step-by-step explanation

The radius of a circle is the distance between the centre and the circumference of the circle.

Radius is half the diameter.

From the diagrams given; D and H are not the diameters.

In circle G, the diameter is 10. So, its radius is 5.

In circle F, the diameter is 20. So its radius is half of 20. That is 10.
