...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 ...

...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. y=+SQRT(16-x^2) and

...your answer. x^2 + y^2 = 5 The equation of a circle is (x-h)^2+(y-k)^2=r^2. Since h and k are 0, we have x^2 + y^2=r^2. Since r= 5, r^2=25. Thus, the equation is x^2 + y^2 = 25. Good luck. ...

...equation in standard form for the circle with radius 1 centered at the origin. The formula for a circle in standard form in (x-h)^2 + (y-k)^2 = r^2, where r is the radius, the point (h,k) is the ...

circle equation how do you measure diameter If you know the center, measure the distance between the center and one point on the circumference. Measure with the opening of a compass and report on a ...

...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

circle the equation of which is X^2+Y^2=4, a circle centered at the origin with radius 2. When you isolate Y^2 and then extarct the squre root you obtain two solutions, call them Y1 and Y2 Y1=SQRT(4-X

...equation of a circle of center (1,1) and radius 5 To graph it isolate y as +/- SQRT (25-(x-1)^2) or use the CONICS application, which you can download from education.ti.com You can also use the Cabri ...

...equation of a circle centered on (0,0) and with radius r=3. You can draw it as a conic section.For that you will need the conics application. Look for it on education.ti.com You can also draw it as ...
