Answer:
Radius: 7.5 cm ; Diameter: 15 cm
Step-by-step explanation:
The radius of a circle is basically the middle "halfway" point and in this case, it has already been given, 7.5 cm. The diameter is the middle line of the circle and to find the diameter, you must multiply the radius by 2, which is essentially 7.5 cm*2, and this gives you a diameter of 15 cm.
