Answer:
for #2 I'm pretty sure he makes $10 per hour
Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :

Also,

Where
is the angular speed
So,

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
The rational exponent expression of sixth root of f is <span>f to the one sixth power
proof
A^1/n, is called n-th root of A, for all n differ from zero</span>
I think the answer is 6cm, 8cm, 10cm
