Answer: 
Step-by-step explanation:
The answer is that his average is 75.5 for the second nine weeks
√120 ≈ 10.95
and 10.95²≈ 120
therefore each side of this square room is about 10.95 feet.
Area = pi*r^2
Circumference = 2pi*r
Step 1: find the radius from area
81pi=pi*r^2
81=r^2
9=r
Step 2: plug in radius to the circumference equation
Circumference = 2pi*r
18pi is the answer, otherwise know as 56.52 as well.

<h3>How to represent the bundle of toothpicks</h3>
The bundle is given as:
Bundle = 62
