Find the area of a circle with a circumference of 6.28 units.

19.73 units.

Step-by-step explanation:

the area of a circle can be found with the equation C=2πr.

first, find the radius of the circle by dividing 6.28 by 2.

6.28/2 = 3.14

next, set up the equation.

C = 2 · π · 3.14

C = 2 · 3.14 · 3.14

C = 19.73

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

50- 250 is correct i did that one too
