Answer:

2.65 cm to the nearest hundredth

Step-by-step explanation:

A = πr^2 = 5.5

r^2 = 5.5/ π = 1.5707

r = 1.3231

Diameter = 2 * r

= 2.6462.

Answer:

2.64cm

Step-by-step explanation:

A = π r^2

5.5 = π r^2

1.75 = r^2

r = 1.32

Diameter is then 2(1.32) = 2.64

In algebra, we often study relationships where a change to one variable causes change
bearhunter [10]

A familiar situation describing where one quantity changes constantly in relation to another quantity is: <em><u>the amount you pay as </u></em><em><u>cost </u></em><em><u>for buying gas at a gas station in relation to the </u></em><em><u>quantity of gas</u></em><em><u> you buy.</u></em>

<em><u /></em>

The two quantities, <em><u>(</u></em><em><u>cost </u></em><em><u>and </u></em><em><u>quantity </u></em><em><u>of gas) are </u></em><em><u>directly proportional</u></em>.

When you represent the relationship of cost of gas and quantity of gas on a graph, you will have: a proportional graph with cost ($) on the y-axis and quantity of gas (gallons) on the x-axis.

<em>(see attachment for how the </em><em>graph </em><em>will look like.)</em>

<em><u>There are usually two </u></em><em><u>variables</u></em><em><u>: </u></em>

  • Independent variable which causes the change.

  • Dependent variable which responds to the change caused by the independent variable.

A situation where one quantity (dependent variable) changes constantly in relation to another quantity (independent variable) is a situation of the amount you pay at a gas station for filling your car with a certain quantity of gallons of gas.

The two quantities are directly proportional to each other.

<em>That is:</em>

  • The cost of gas in dollars (independent variable) is directly proportional to the quantity of gas in gallons (dependent variable).

  • As the quantity of gas increased in gallons, there would be equal increase in the cost of gas in dollars you would pay.

If we are to represent this on a graph, the graph will be a straight line graph showing a proportional relationship between cost of gas (on the y-axis) and quantity of gas (on the x-axis)

<em>(see the image in the attachment below).</em>

<em>Therefore:</em>

  • A familiar situation describing where one quantity changes constantly in relation to another quantity is: <em><u>the amount you pay as </u></em><em><u>cost </u></em><em><u>for buying gas at a gas station in relation to the </u></em><em><u>quantity of gas</u></em><em><u> you buy.</u></em>

<em><u /></em>

  • The two quantities, <em><u>(</u></em><em><u>cost </u></em><em><u>and </u></em><em><u>quantity </u></em><em><u>of gas) are </u></em><em><u>directly proportional</u></em>.

  • When you represent the relationship of cost of gas and quantity of gas on a graph, you will have: a proportional graph with cost ($) on the y-axis and quantity of gas (gallons) on the x-axis.

<em>(see attachment for how the </em><em>graph </em><em>will look like.)</em>
