This circle is centered at the origin, and the length of its radius is 6. what is
the circle's equation?

X^2+y^2=36

Step-by-step explanation:

If a circle is centered at the origin, and the length of its radius is 6, the circle's equation is X^2+y^2=36.

Radius = 6

x² + y² = 36

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← r is the radius

here r = 6, so

x² + y² = 6², that is

x² + y² = 36

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
