Question

Write the equation of the circle with center (-11, 3) and radius r = 9. Use the ^ key for the exponents. Write your answer as the example:
(x - 4)^2+(y+8)^2=25

Answer 1

(x+11)^2 + (y-3)^2 = 81

Answer 2

Write the equation of the circle with center (3, 2) and radius r = 7. Use the ^ key for the exponents. Write your answer as the example:
(x - 4)^2+(y+8)^2=25

Answer 3

in general, equation of a circle with center at A,B and radius R is
(x-A)^2+(y-B)2 = r^2

Answer 4

(x-3)^2 + (y-2)^2 = 49

Answer 5

A and B are the x and y of the center you want. so for this case, A=3, B=2 and r=7 just substitute in dhatraditya's formula.
