Answer:
100.48 inches
Step-by-step explanation:
Essentially the distance a circle covers after a rotation is the same as the length of the circumference ( outline of the circle ).
So basically we need to find the circumference and multiply that by 2 ( because we are looking for the distance covered by the wheel after 2 rotations )
Circumference = 2πr
where r = radius
the given radius is 8, so r = 8
we then plug in the value of the radius into the formula for circumference
C = 2πr
r = 8 and π = 3.14 ( approximately )
C = 2(8)(3.14)
2 * 8 = 16 and 16 * 3.14 = 50.24
So one rotation covers a distance of 50.24 inches
2 rotations cover 50.24 * 2 = 100.48 inches
