How many feet does a wheel with a radius of 16 inches travel after 4 hours?
Solution:
I know the circumference must be found.
However, I notice that the radius is given here not the diameter.
Let d = diameter
Let r = radius
d = 2r
d = 2(16 inches)
d = 32 inches
C = pi(32 inches)(4 hours)
Is this the correct set up?
