The formula for the circumference of a circle (which will give us the amount of rubber stripping needed) is:
Circumference = Ο * diameter
Plugging in the given circumference of 94.2 inches, we can solve for the diameter:
94.2 = Ο * diameter
diameter = 94.2 / Ο
diameter β 30 inches
The formula for the area of a circle (which will give us the amount of felt needed) is:
Area = Ο * radius^2
Since the diameter is twice the radius, we can calculate the radius as half of the diameter:
radius = 30 / 2 = 15 inches
Plugging in the radius, we can solve for the area:
Area = Ο * 15^2
Area = Ο * 225
Area β 706.86 square inches
Since the width of the rectangular piece of felt is equal to the diameter of the wheel (30 inches), the length needed can be found by doubling the radius and adding a little extra for cutting errors:
Length = 2 * 15 + extra
Length = 30 + extra
Therefore, the rectangular piece of felt would need to be at least 30 inches plus some extra length in order to cover each wheel completely.
