First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.

Answer:
18
Step-by-step explanation:
x= Chargers
x+14= Vikings
x + x + 14 = 50 Combine the x's to be 2X
2x + 14 = 50 Subtract 14 from both sides
2x -14 = -14
2x = 36 Divide 2 into to 2x and 36
2x /2 = 36 /2
x= 18
