Expert Answers

An illustration of the letter 'A' in a speech bubbles

The distance between the point (5,4) and (2,0) is sqrt(9 + 16) = 5

As the center of the circle is (2,0) and the point (5,4) lies of it, the distance between the points is equal to the radius.

The equation of the circle is (x - 2)^2 + (y...

The distance between the point (5,4) and (2,0) is sqrt(9 + 16) = 5

As the center of the circle is (2,0) and the point (5,4) lies of it, the distance between the points is equal to the radius.

The equation of the circle is (x - 2)^2 + (y - 0)^2 = 25

=> x^2 - 4x + 4 + y^2 = 25

=> x^2 + y^2 - 4x - 21 = 0

The equation of the circle is x^2 + y^2 - 4x - 21 = 0
