write the standard form of the equation and the general form of the equation of the circle with radius r and center (h,k)
r=10; (h,k)=(8,6)

Given: C(h,k) = C(8,6), r = 10.
STD Form: (xh)^2 + (yk)^2 = r^2.
(x8)^2 + (y+6)^2 = 100.
x^216x+64 + y^2+12y+36100 = 0.
X^2 + Y^2 16x + 12y  64 = 0
Gen. Form: X^2 + Y^2 Ax + By + C = 0.
