Answer:
32 cm
Explanation:
The radius is the distance from the center of a circle to its outside edge; this means it goes halfway across the circle. The diameter is the distance from one edge of a circle to the opposite edge, passing through the center. This means it goes completely across the circle.
This means the radius is half of the diameter. Since the radius is 16, the diameter will be 2(16) = 32 cm.
