Question

The equation of the circle below is x2 + y2 = 5.
TRUE OR FALSE?

Answer 1

FALSE

The standard form of the equation of a circle is


`(x - a) {}^(2) + (y - b) {}^(2) = r {}^(2)`

With (a, b) representing the centre and r representing the radius.

The radius of the circle in the attachment is 5, and therefore the circle has the following equation.


`{x}^(2) + y {}^(2) = 25`
