Find the equation of a circle with
Centre (2, 4) and radius 5
The general form of the equation of a circle is:
(x - h)2 + (y - k)2 = r2
Where, (h, k) is the centre of the circle.
r is the radius of the circle.
Substituting the centre and radius of the circle in he general form:
⇒ (x - 2)2 + (y - 4)2 = 52
⇒ (x - 2)2 + (y - 4)2 = 25
Ans; equation of a circle with Centre (2, 4) and radius 5 is:
⇒ (x - 2)2 + (y - 4)2 = 25
