Question 768547
<pre>
Establish the equation of a circular object whose radius equals 6 centimetres and centre's coordinates are (3, 2).

Equation for a circle with radius r and centre at (a,b) is given by
{{{(x - a)^2 + (y - b)^2 = r^2}}}

Here, a = 3, b = 2, r = 6
Just substitute in the above formula to get the equation.

{{{(x - 3)^2 + (y - 2)^2 = 6^2 = 36}}}

Expand the left hand side and simplify, to check which of the choices is correct.

Hope it is clear :)
