1 ft = 12 in
2 ft = 24 in
r = 24 in = 2 ft
The volume of a ball:
V = ( 4 / 3 ) * pi * r ^ 3 =
( 4 * pi / 3 ) * 2 ^ 3 =
( 4 * 3.1416 / 3 ) * 2 ^ 3 =
( 12.5664 / 3 ) * 2 ^ 3 =
4.1888 * 2 ^ 3 =
4.1888 * 8 = = 33.5104 ft ^ 3
Jack is going to fill his beach ball with water. The radius of the ball is 24in. How much water will it take to fill the beach ball?
4/3(3.14)
4.19 (2)^3
4.19 (8)
33.52
Instead of using 24in. I used 2ft. Instead since 24in. Equals 2 ft.
