Now if I give you the answer how are you going to learn anything about this? Your only asking for a flowchart. I will give you a hint. break the problem down. All the information needed except the Formulas used is in your post.

### Area of circle

(pi)R squared (Fixya won't let me use the sign for Pi)

example: suppose the radius of a circle is 10 inches, then the Area of the circle would be pi times 10 times 10 or 100*pi

pi represents the circumference (distance around) of a circle / diameter and for any circle is constantly the same number which is approximately 3.14

so in my example 100*pi=100*3.14 or 314 square inches

### WHAT ARE THE MATHEMATICAL FORMULAS FOR A CIRCLE?

A circle is the set of points equidistant from a given point, so
(x-a)^2 + (y-b)^2 = c will define a circle, where a and b are the coordinates of the center and c is the square of the radius.

### WHAT ARE ALL OF THE MEASUREMENTS OF A CIRCLE CALLED

The radius and the coordinates of the center will completely define a circle. Some other measurements include the diameter, circumference, and area. Then there are parts of the circle, such as arc and chord.

### To graph a circle with radius 4

Press [2nd][PGRM] to open the (DRAW) utility. Scroll down to reach the line 9: Circle( and press ENTER. Complete the command by supplying the coordinates of the circle center and the radius.
Circle(0,0,4) draws a circle with center at the origin (0,0) and radius 4.
By the way the equation of a circle is not a function. You have to cut it into the upper brach and the lower part to graph it.

### WHEN GRAPHING A CIRCLE ON THE TI83, THERE ARE POINTS MISSING.

Use the DRAW program.
Press [2nd][PRGM] (DRAW)
Select [9:Circle (]
Command echoes on main screen
Complete the command with coordinates of the center and the radiius
Close parenthesis and press [ENTER]
The circle is displayed.

Ex: Circle(0,3,2) draw a circle with cntere at (0,3) and radius equal to 2.

Alternatively: If the conics application is on the calculator run it.
Press [APPS]
Select [Conics]
Select [1:CIRCLE]
Choose the canonical form (X-H)^2 + (Y-K)^2=R^2 where H, and K are the coordinates of the center and R is the radius.
You will be prompted to enter the values for H,K, and R

You can also use the general equation for a circle aX^2 +aY^2+BX+CY +D=0
Enter the values of a, B, C and D.Change the values to get what you want.

### What is the radius of a 30'' pipe

30" diameter? Radius is 15" (half of diameter).

30" circumference (distance around) is a little more complicated...

The number is the ratio of the circumference of a circle to the diameter. The value of is approximately 3.14159265358979323846...The diameter of a circle is twice the radius. Given the diameter or radius of a circle, we can find the circumference. We can also find the diameter (and radius) of a circle given the circumference. The formulas for diameter and circumference of a circle are listed below. We round to 3.14 in order to simplify our calculations.

### Analytic geometry

assuming the question is what is the circle equation?
and if (-2,2) is the center of the circle
the equation should look like this: (x+2)^2+(Y-2)^2=R^2

And now only R is needed.

given 2x-5y+4=0 equation of line perpendicular

we can rearange the equation to be y=(2x+4)/5
from that we can see that the slope of the line is 2/5
And from the fact of perpendicular line we can say that the slope
of the radius line is -2/5.

The motivation now is to calculate the distance between the center of the circle to the cross point of the radius with the line perpendicular

For that we would calculate the radius line equation and compare it to the equation of line perpendicular

As mentioned earlier the slope of the radious line is -2/5.

So the equation is y=-2/5x+b and b can be calculated by using the center of the circle coordinates

2= - (2/5)*(-2)+b ------> b=2-4/5=1.2

Now the cross point is calculated by comparing the equations:
-(2/5)x+1.2=(2x+4)/5 --> -2x+6=2x+4 --> 4x=2 --> x=1/2 --> y=1

So the cross point is (1/2,1).

The distance between the points is calculated by the following
Formula:

R=SQR(((1/2)-(-2))^2+(2-1)^2)=SQR(2.5^2+1^2)=SQR(6.25+1)=
SQR(7.25)

Therefore the circle eq is (x+2)^2+(Y-2)^2=7.25

### Creating a ring using two circles in c++ program

Nice try!

If nobody has helped you since September 2008, when you asked the question, you probably scored a "zero" in your computer-programming course, and probably don't need an answer to your "homework" assignment.
