What is the volume of one rubber ball? round to the nearest hundredth of a centimeter. cm3 if the price of the rubber needed to
sertanlavr [38]

The cost of producing one ball will be $ 0.09261. Then the profit will be if each ball is $ 0.41.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A toy company produces rubber balls that have a radius of 1. 7 cm.

A sphere has a radius of 1. 7 centimeters.

Then the volume of the ball will be

Volume = 4/3 x π x r³

Volume = 4/3 x π x 1.7³

Volume = 20.58 cubic cm

If the price of the rubber needed to produce a ball is $0.0045/cm³.

Then the cost of producing one ball will be

→ 20.58 x 0.0045

→ $ 0.09261

If the company sells a ball for $0.50. Then the profit will be

Profit = 0.50 - 0.09261

Profit = $ 0.41

What is the third quartile of this data set 20,21,24,25,28,29,35,37,39,42,44
dezoksy [38]

Answer:

The third quartile would be <u>39</u>.

Step-by-step explanation:

• Since the numbers are already in order, the next step would be to find the median:

- The <u>median</u> is the middle number; found by ordering all data points and picking out the one in the middle.

  • The median would be 29.

• The <u>first quartile</u>, is denoted as Q1 and is the middle number that falls between the smallest value of the data set and the median.

  • The first quartile would be 24.

• The <u>third quartile</u>, is denoted as Q3 and is the median of the upper half of the data set.

  • The third quartile would be 39.
