Area of a circle is pi x radius^2
Area = pi x 22 ^2
Area = pi x 484
Area = 1,519.8 mm^2
Answer:
4.50
Step-by-step explanation:
2.25 times (100/(sale percentage)), so 2.25 x 2
Answer:
3(48-343y^3)
Step-by-step explanation:
we have
the equation of the line is 
the points are

<u>Method 1</u>
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
In this problem we have a direct variation
The constant of proportionality k is equal to the slope of the line

so

therefore
<u>the answer is</u>
the slope of the line is equal to

<u>Method 2</u>
we know that
the formula to calculate the slope between two points is equal to

we have

substitute in the formula



therefore
<u>the answer is</u>
the slope of the line is equal to

Answer:
$15, $8, $1, respectively
Step-by-step explanation:
Line up the number of years with the line and check the pay.
