The polynomial – 24x2 + 333x – 137 represents the average number of visitors (in thousands) per day to a park area, where x represents the month of the year. Use this model to predict the average daily attendance at the park for the month of April. (Hint - April is the fourth month.)

Given that we need to determine the radius of the circle.

Radius:

By definition of radius of circle, the radius is the  length of the line which is drawn from the center of the circle to any point on the circle.

From the figure, we need to determine the radius of the circle.

As, we can see that, the distance from the center of the circle to the point on the circle is 11 cm.

Since, we know that, the radius is the distance from the center of the circle to the point on the circle then, the radius of the given circle is 11 cm

Thus, radius of the circle is 11 cm.
