Kiah wants to buy a flying disc for his friend. The radius of the disc is 15 cm. What is the length of the diameter?(1 point) cm
The diameter of a circle is equal to twice the radius.
So the diameter of the flying disc with a radius of 15 cm would be:
2 x 15 cm = 30 cm
Therefore, the length of the diameter of the flying disc is 30 cm.
