Answer:
If the radius is 37 units, the equation of the circle is
x² + y² - 2.6x + 7y - 1355.06 = 0
If the units is actually 3.7 units, then the equation becomes
x² + y² - 2.6x + 7y + 0.25 =0
Explanation:
The general equation of a circle is given as
(x - a)² + (y-b)² = r²
where a and are the center of the circle along the x and y axis respectively.
Hence a circle that has a radius of 37 units and is centered at (1.3, -3,5) may be given as
(x - 1.3)² + (y + 3.5)² = 37²
x² - 2.6x + 1.69 + y² + 7y + 12.25 = 1369
x² + y² - 2.6x + 7y - 1355.06 = 0
If the units is actually 3.7 units,
x² + y² - 2.6x + 7y + 0.25 =0
