Answer:
radius=7.5
diameter=15
Step-by-step explanation:
The radius is given to be 7.5
The diameter is twice that which is 15
radius = 7.5 cm
diameter = 2*radius = 2 7.5 = 15cm
The radius is the distance from the center to the any point on the circle. The diameter goes across the circle through the center and is double the radius.
