Question 851811: Write the standard equation of a circle with each given radius and center.
1. r = 4; C= (0, 0)
2. r = 1; C = (2, 3)
3. r = 4; C = (-2, 8)
Write the standard equation for the circle given the following equations.
4. x^2 + y^2 - 8x + 7 = 0
5. x^2 + y^2 + 4x - 6y - 3 = 0 Answer by ewatrrr(24785) (Show Source):
Hi,
Standard Form of an Equation of a Circle is
where Pt(h,k) is the center and r is the radius
1 - 3 use above, substitute values given
4 & 5 Completing the Square:
4. (x-4)^2 + y^2 = -7 + 16 = 9
(x+2)^2 + (y-3)^2 = 3 + 4 + 9 = 16
