What is asked in the problem is simply the volume of the solid rubber ball. The volume of sphere given the diameter may be calculated by,
V = πd^3 / 6
Substituting the given value of diameter,
V = (π x 3³) / 6 = 9π/2 or 14.14
Thus, one needs approximately 14.14 in³ of material.

➷ Use this formula:
density = mass / volume
Rearrange it for mass:
mass = density x volume
Substitute the values in:
mass = 100 x 19.3
Solve:
mass = 1930g

<em><u>Answer: 10.</u></em>
<em><u /></em>
<em><u>Step-by-step explanation:</u></em>
<em><u>DIVISION. 120/12.</u></em>
<em><u>That is hard! Here's a trick.</u></em>
<em><u>12x9= 99=9=108. Or 12x6=66+6=72.</u></em>
<em><u>We will stick with 12x9, that equals 108.</u></em>
<em><u>We should add another 12 until we get to 120. </u></em>
<em><u>108+12=120. That is 10 times. The trick was...</u></em>
<em><u>dividing by 12 is hard, so lets say 12x4. I can put 4 and 4 together.</u></em>
<em><u>44 then and another 4. That is 48. So 12x4=48.</u></em>

Determine the number of bags sold
First, we need to determine the number of bags for 27 pears;
Since they are packed in 3s
Hence:
9 bags were used for 27 pears;
After 5 bags were sold, we have:
Recall that the pears are packed in 3s
So:
