Answer:
Bet
Step-by-step explanation:
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.
That would be week 2 and 4 (B). They are both at 12 students attending

(2x^2+13x+15)/2x+3=x+5
Use long or synthetic division to solve this problem.
There is 12 inches in a foot. Times inches by feet. You can pick a number for the feet and do trial and error until you get a number the closet to 55.
12 inches times 4 feet equals 48 inches.
12x4= 48
Now subtract 55 inches from 48 inches
55-48= 7 inches
So 4 feet and 7 inches tall
