Question

Plz help ASAP 20 points 10. What is the equation of a circle with radius, r = 4, and the center at (0,0)?

A.X² + y² = 4
B.22 + y2 = 16
C.2 - 4)+ (y – 4) = 4
B.(.2 - 4)? + (y – 4)2 = 16

Answer 1

The answer that you are looking for is A. X2 + y2 = 4

Answer 2

a

Explanation:

the equation for a circle centered at orgin is x^2+y^2=r where r is the radius. multiplying, adding, or subtracting any numbers to the x and y components such as the other choices here causes the circle to be translated about the graph.
