Find the radius and diameter of a Frisbee with a circumference of 11π inches.

radius = 5.5 inch

diameter = 11 inch

Step-by-step explanation:

Circumference = 2πr     Formula to find the radius

11π = 2π (r)       Plug numbers into the equation

5.5 = r         Divide both sides by 2 to isolate the variable (r)  

(x + 7)^2 + (y + 3)^2 = 4

Step-by-step explanation:

The standard equation of a circle is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. We can substitute the information given to obtain:

(x + 7)^2 + (y + 3)^2 = 4
