Answer: The exact circumference of the circle is $10\pi[\tex] in.Step-by-step explanation:Since, the circumference of a circle is,[tex]C=2\pi r$

Where, r is the radius of the circle,

Here, r = 5 inches,

Hence, the circumference of the circle is,

$C = 2\pi(5) = 10\pi\text{ in}$

Thus, The exact circumference of the circle is [tex]10\pi[\tex] in.

A graph is shown below:

Zanzabum

The general equation of a line is expressed as y = mx + b where m is the slope of the line and b is the y-intercept. The y-intercept is the value of y when the graph crosses the y- axis. Consequently, it is the value of y when x is zero. The slope is the rate of change of y with respect to the change in x. It is calculated from the ratio of the difference of two y values and the difference of the corresponding x values. Given the points would result to a line, we can determine those elements for the line as follows:

b = 36
m = (y2 - y1) / (x2 - x1)
m = (27 - 36) / (3 -0) = -3

So, the equation of the line would be y = -3x + 36.
