What is the equation of a circle with center (–7, –2) and radius 4?

(x + 7)² + (y + 2)² = 16

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, - 2) and r = 4

(x - (- 7))² + (y - (- 2))² = 4²

(x + 7)² + (y + 2)² = 16 ← equation of circle

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
