The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.
Answer:
1
Step-by-step explanation:
1/2 = 3/6
2/3 = 4/6
3/6 + 4/6 = 7/6
7/6 - 1/6 = 6/6 or 1
