If RS is the diameter of the circle, then the midpoint of RS will be the center of the circle.
Equation of a circle:
(where (h, k) is the center and r is the radius)
Substituting found center (-2, 2) into the equation of a circle:
To find , simply substitute one of the points into the equation and solve:
Therefore, the equation of the circle is:
We are given that a house had a value of $245000 and its value was increased by 9%. To determine how much is this value increase in dollars we need to multiply the value of the house by 9/100. We get this:
Therefore, the increase in dollars is $22050. Now, to determine the current value we need to add the increase to the previous value, we get:
Therefore, the current value of the house is $267050.
