<h3>Answer: 12pi millimeters</h3>

======================================================

Explanation:

The circumference of a circle is the distance around the full circle, aka the perimeter.

The formula for the circumference is

C = pi*d

where d is the diameter. The radius given is 6, so the diameter is 2*6 = 12.

The circumference, is therefore:

C = pi*d

C = pi*12

C = 12pi millimeters

---------

As a slight alternative, you can use this formula

C = 2*pi*r

with r = 6 as the radius

C = 2*pi*r

C = 2*pi*6

C = 2*6*pi

C = 12pi

We get the same answer as before.

W are r are not valid grades. I have attached the table associated with this question

Answer:
GPA = 3.625

Explanation:
GPA stands for "Grade Point Average".
It can be easily calculated by dividing the total grade points with the total number of hours.
Taking a look at the table, we can find that:
Total grade points = 29
Total hours = 8
Therefore:
GPA = 29 / 8 = 3.625

Hope this helps :)
