step 1
Find the radius of the circle
To find out the radius, calculate the distance between the center and any point that lie on the circle
so
(-2,3) and (-2,0)
Its a vertical distance
so
r=3-0=3 units
step 2
we have the radius r=3 units and the center (-2,3)
the equation of the circle is
*expanded form: 6/10 + 3/100 + 2/1000 (that is not division those r fractions!)
*written: six hundred thirty-two thousandTHS
always put "ths" when it is after a decimal point.
