Answer:
140 degree
Step-by-step explanation:
The sum of the interior angle measures in a regular polygon is 1260 degree.
(n-2)*180=1260
180n-360=1260
180n=1260+360
180n=1620
n=1620/180
n=9
Now, evaluate the measure of one of the interior angles of the polygon.
((9-2)*180)/9=140 degree.

The circumference of wheel is 6.28 feet.
Step-by-step explanation:
Given,
Area of prize wheel = 3.14 square feet
Area = πr²

Dividing both sides by 3.14

Circumference = 2πr
Circumference of prize wheel = 
Circumference of prize wheel = 6.28 feet
The circumference of wheel is 6.28 feet.
