A diagram of a swimming pool is shown. 3.5 m
Vhat is the approximate circumference of the swimming pool? Use 3. 14 as an estimate for t.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
