After taking part in a competition Juan received a gold medal with the diameter of 20 centimeters what is the medals radius

Answer 1

The radius of the gold medal is 10 centimeters.

To find the radius, you need to divide the diameter by 2, since the diameter is the distance across the circle passing through its center.

Radius = Diameter / 2
Radius = 20 cm / 2
Radius = 10 cm
