Question

help please

Answer 1

The radius of a fully inflated soccer ball is 4.5 inches. After using the ball for a game, the match referee, Jason, measured the ball’s radius and found it had decreased to 4.4 inches.

Ignoring the thickness of the materials the soccer ball is made from, find the volume of the ball before and after the match, and find the difference of the volumes before and after the match. Use π=227.

The approximate volume of the ball before the match is(95.46, 274.36, 381.86, or 406.24) cubic inches. The approximate volume of the ball after the match is (89.24, 321.48, 356.96, or 374.74) cubic inches. The approximate change in the ball’s volume before and after the match is(6.22, 24.90, 31.50, or 47.12) cubic inches.

Answer 2

*use pi=22/7

Answer 3

do you know how to find the volume of a sphere?

Answer 4

yes

Answer 5

ok. so did you try finding the volume of either of the ball yet?

Answer 6

no i dont know why it says use pi=22/7

Answer 7

i get 121.5 for the first one but its not an option

Answer 8

ok nvm i left out pi

Answer 9

ok
