Question

PLZ use the information given to write the equation of the circle.

Center: (0,-16), Radius: √15


A: x2+(y+16)2 = 15−−√

B: (x+16)2+y2=15

C: x2+(y+16)2= 15

D: x2+(y−16)2 = 15

Answer 1

x^2+(y+16)^2=15

Explanation:

(x-0)^2+{y-(-16)}^e=(√15)^2

→x^2+(y+16)^2=15

Answer 2

• C. x² + (y + 16)² = 15

Explanation:

Equation of circle:

• (x - h) + (y - k) = r², where (h, k) is the center and r is the radius

We have:

• h = 0, k = -16, r = √15

Substitute the given into the equation above and get the equation of the given circle:

• (x - 0)² + (y - (16))² = (√15)² ⇒
• x² + (y + 16)² = 15

Correct choice is C
