Hello!
To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.
C = 2(36)π
C = 72π
Therefore, the circumference of the circle is 72π inches.
Given:

x lies in the III quadrant.

Answer: The answer is 1296
Alright, so we know that there are 7 days a week with 24 hours per day.
24x7= 168 hours a week.
Convert the problem to an equation using the percentage formula: P% * X = Y.
Let's take the 40% that is Sleep and use it in the percentage formula with the 168 hours.
40%x168= roughly 67 hours.
Hope this helped!
