Use the given graph. determine the period of the function.

Step-by-step explanation:

we know that

The period of a periodic function is the interval of x-values on which the cycle of the graph that's repeated in both directions lies.

so

see the attached figure to better understand the problem

To calculate the period subtract from

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
