Area of the circle
A = πr²,
r is a radius of the circle.
Formula of the circle is
(x - h)² + (y - k)² = r²,
h,k are coordinates of a center of a circle.
(x - 2)² + (y - 3)² = 24
For this circle r² = 24.
A = πr², -------> A=24π is the exact value of the area.
A=24π≈ 75.40 is the approximate value of the area.
