Answer:
17.8 cm³
Step-by-step explanation:
The radius of the roll is half the diameter, so is 9 mm. The length of the roll of 50 dimes is 1.4·50 mm = 70 mm. With these dimensions, we can use the formula for the volume of a cylinder:
V = πr²h = π(9 mm)²(70 mm) = 5670π mm³ ≈ 17,812.8 mm³
Perhaps a more convenient unit of measure is cm³. Each cm³ is 1000 mm³, so the volume of a roll of dimes is approximately ...
V ≈ 17.8 cm³
32 / 4 = 8
8 * 3 = 24 = already brought in permission slips.
8 * 1 = 8 = did not bring in permission slips.
So your answer is 8.
50/1 * 1/25 = 50/25 = 2
75/1 * 1/25 = 75/25 = 3
