Answer:
The volume of a rubber ball is 20.57 cm³ .
The cost of producing one ball is $ 0.093 .
The profit will it make on each ball is $ 0.41 .
Step-by-step explanation:
Formula
Where r is the radius of the sphere .
First part
As given
A toy company produces rubber balls that have a radius of 1.7 cm.
r = 1.7 cm
Put all the values in the formula
Volume of a rubber ball = 20.57 cm³ (Approx)
Therefore the volume of a rubber ball is 20.57 cm³ .
Second part
As given
If the price of the rubber needed to produce a ball is $0.0045/cm³.
Thus
Total cost of producing a rubber ball = Volume of a rubber ball × Price of the rubber needed to produce a ball .
Put all the values in the above
Total cost of producing a rubber ball = 20.57 × 0.0045
= $ 0.093 (Approx)
Therefore the cost of producing one ball is $ 0.093 .
Third part
If the company sells a ball for $0.50 .
i.e
Selling price of a ball = $0.50
The cost of producing one ball is $ 0.093 .
i.e
Cost price of a ball = $0.093
Profit = Selling price - Cost price
Put all the values in the above
Profit = $ 0.50 - $ 0.093
= $ 0.41 (Approx)
Therefore the profit will it make on each ball is $ 0.41 .
