Answer:
30
120
706.5
Step-by-step explanation:
circumference= 94.2 inches, circumference is pi x diameter so-
diameter = 94.2/pi inches.
Using 3.14 as an approximation for pi we get:
Diameter=30 inches.
So would need a length of at least
4x30 = 120 inches of felt for four wheels.
The area of the circular wheel is pi x diameter 2/4 square inches.
Area is 706.5 square inches which is how much felt is needed to cover one wheel.
