NEED THIS ASAP Write the equation of a circle with a center at (1, 4) where a point on the circle is (4, 8).
1 answer:
Answer:
(x-1)^2 + (y-4)^2 = 5^2
Step-by-step explanation:
Using the standard equation of a circle with center at (h, k) and radius r:
(x-h)^2 + (y-k)^2 = r^2, we substitute 1 for h, 4 for k, 4 for x and 8 for y:
(4-1)^2 + (8-4)^2 = r^2, or
9 + 16 = 25 = r^2
Thus, the radius is 5
and the equation is (x-1)^2 + (y-4)^2 = 5^2. This matches the 2nd answer choice.
