Answer:
0.37 feet.
Step-by-step explanation:
The following data were obtained from the question:
Volume (V) = 4100 ft³
Height (h) = 1.8 miles
Radius (r) =?
Next, we shall convert 1.8 miles to foot.
This can be obtained as follow:
Recall:
1 mile = 5280 ft
Therefore,
1.8 miles = 1.8 × 5280 = 9504 ft
Finally, we determine the radius as follow:
Volume (V) = 4100 ft³
Height (h) = 9504 ft
Pi (π) = 3.14
Radius (r) =?
V = πr²h
4100 = 3.14 × r² × 9504
4100 = r² × 29842.56
Divide both side by 29842.56
r² = 4100/29842.56
Take the square root of both side
r = √(4100/29842.56)
r = 0.37 ft
Therefore, the radius of the hole is 0.37 feet.

The total cost of hard drive is $29.96
Step-by-step explanation:
Given,
Original price = $40
Discount = 30%
Discount amount = 30% of $40 = 
Discount amount=
Price after discount = Original price - discount amount
Price after discount = 40-12 = $28
Tax rate = 7%
Tax amount = 7% of price after discount
Total cost of hard drive = Price after discount + Tax amount
Total cost of hard drive = 28+1.96 = $29.96
The total cost of hard drive is $29.96
