The circumference of a circle is 19pi ft. What is the area, in square feet? Express your answer in terms of pi.

A = 90.25 pi ft^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi* r

19pi = 2 * pi * r

Divide each side by 2pi

19pi/2pi = 2 * pi *r/2pi

9.5 = r

Now find the area

A = pi r^2

A = pi ( 9.5)^2

A = 90.25 pi ft^2

Step-by-step explanation:

Circumference is found in

while area is

Since we know the circumference value, we can plug it in and solve for r:

Since and , then

and

The pi's cancel out, leaving us with the fact that

We will use that now in the area formula:

so

A = 90.25π

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
