Question

What is the equation of the circle?

O A x2 + y2 = 1
+
1 2
OB +2
O a x²+2 = 1
o a 2
D. p + 12 = 2

Answer 1

A

Explanation:

x2+y2=0.25

This is the form of a circle. Use this form to determine the center and radius of the circle.

(x−h)2+(y−k)2=r2

Match the values in this circle to those of the standard form. The variable (r) represents the radius of the circle, (h) represents the x-offset from the origin, and (k) represents the y-offset from origin.

r=0.5

h=0

k=0

The center of the circle is found at

(h,k).

Center: (0,0)

These values represent the important values for graphing and analyzing a circle.

Center: (0,0)

Radius: 0.5
