In circle o, radius oq measures 9 inches and arc pq measures 6 pie inches. what is the measure, in radians, of central angle poq? edge

The circle has circumference . If , then

Step-by-step explanation:

We know that the formula to calculate the length of arc having central angle 'x' is given by :-

, where r is radius of the circle.

Given : In circle O, radius OQ =

The measure of arc PQ =

The measure of central angle POQ ( in radians ) is given by :-

Hence, the measure of central angle POQ =

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
