Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.
The <span>approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.
i.e.

40/9 *3/8=5/3 zThats the answer
The answer is A:
Because the only difference between the rest of the answer choices are the lower and upper quartiles, that is all you need to find. In order to do so you find the median for the first half (lower quartile) and then find the median for the second half. In this case it is 29 (Q1) and 58 (Q2)
Isolate the x. Root both sides
√x²< √81
x < 9 is your answer
hope this helps
Cost = number of objects x price per object
$1,475 = x boxes * $25
x = 1,475/25 = 59 boxes of diapers
