Question

Write the standard form of the equation of a circle with a radius of 1 and a center of (-7,1)

Answer 1

Answer= (x+7)^2 +(y-1)^2 =1

Standard form of a circle:
(x-h)^2 + (y-k)^2 = r^2

Answer 2

Answer:

(x + 7)² + (y - 1)² = 1

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 7, 1) and r = 1 , then

(x - (- 7) )² + (y - 1)² = 1² , that is

(x + 7)² + (y - 1)² = 1
