Question

find radius of the sphere ,r=d/2 for balls of different sizes.note the observation in the .​

Answer 1

Answer:

Explanation:

Since the circumference is equal to πD, which is equal to 2πr, dividing the circumference by 2π will give the radius. If you have a sphere with a circumference of 20 m, find the radius by dividing 20/2π = 3.183 m. Use the same formula to convert between the radius and circumference of a circle.
