The equation of a circle is
.
Step-by-step explanation:
-The equation of a circle is:
(where center is
, the point
and the radius known as
).
-Use the center (5,-4) and the point (5,-2) for the equation:

-Solve the equation:





-After you found the radius, use the center (5, -4) and radius 2 to get the equation of a circle:

-Then, after you have the equation, the radius needs to simplified by the exponent:

Correct. 0.51 × 2.427 = 51 × 2427 / 10×1000
Answer:
