Determine the equation of the circle graphed below
1 answer:
Equation of the circle is (x - 6)² +(y-7)² = 4.
<h3>What is a Circle ?</h3>A figure having round shape and all the points lie on the same plane is called a circle.
Equation of a circle can be formed using centre of the circle and radius of the circle.
(x-h)² +(y-k)² = r²
where (h,k) is the vertex and 'r' is the radius.
From the given graph the centre of the circle is at (6,7)
and radius of the circle is 2 units
(h,k) is (6,7)
and r= 2
Substituting all the values
The equation of the circle
(x - 6)² +(y-7)² = 2² = 4
Equation of the circle is (x - 6)² +(y-7)² = 4
