Answer:
188.49
Step-by-step explanation:
use the diameter to find the circumference..
C = d pi or C = 2r pi
when you plug in 20, you get 62.83
now take that, and multiply it by 3, because the wheels went around three times.
62.83 * 3 = 188.49 inches
i hope this was helpful to you!

State C spent $28.3 million and State D spent $26.3 million.
Step-by-step explanation:
Total spent for tourism = $54.6 million
Let,
The amount spent by State C = x
The amount spent by State D = y
According to given statement;
x+y = 54.6 Eqn 1
x=y+2 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 2
Putting y=26.3 in Eqn 2
State C spent $28.3 million and State D spent $26.3 million.
