Answer:
B and C
Explanation:
radius of a ball is half its diameter, ball C has a diameter less than the inner rim, easily fitting through (13<14)
Ball B has a radius of 6, and since we know that radius is half the diameter, 6 x 2 is 12 and 12 is ball B's diameter. 12 is less than 14 which means ball B can fit through. Hurray!
Ball D has a radius of 8 inches, we need its diameter so 8 x 2 = 16, but 16 is greater than 14, which means ball D cannot fit through. Phooey..
Ball A has a circumference of 45 inches, to get the diameter of the ball when given circumference is simple, just divide the circumference by pi. This works because in order to get the circumference of a ball from diameter we multiply by pi. Now, 45 divided by π (or 3.14) gives us 14.33, 14.33 is ball A's diameter. 14.33 is a little over 14, that means ball A will not fit through the basketball hoop!
I hope this helped!
