The formula c = 2 π r is used to calculate the circumference of a circle when given the radius. what is the formula for calculating the radius when given the circumference?
a) c/2π = r
b) c/2r = π
c) 2 πc = r
d) 2π/c = r

Which function has the smallest y-intercept value

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
