Answer:
$36000
Step-by-step explanation:
We have a mean price of $4500 this means that in the 8 cars we have cars with higer and lower prices than $4500 but that if we have to give the same price to 8 cars that would be $4500. Then to know the total price of the all 8 cars we just have to multiply:

Area = πr^2
π4^2 =16π
=50.3
