Answer: Cost ≈ $3,217
Explanation:
1) Calculate the perimeter (circumference) of the superhighway:
Formula: C = 2πr
r = 4 miles ⇒ C = 2π(4,00miles) ≈ 25132.7 miles
2) Calculate the cost
Formulas:
Cost = number of gallons consumed × cost of a gallon
Number of gallon consumed = galllons per mile × number of miles
Number of gallon = (1 gallon / 25 miles) × 25,132.7 miles = 1,005.3 gallons
Cost = 1,005.3 gallons × $3.20 / gallon ≈ $3,217
Answer:
Cost of gas is around $3217
Explanation:
Given:
Radius of earth = 4000 miles
Gas cost = $3.20/gallon
Mileage = 25 miles/gallon
To determine:
Cost of gas to drive around the earth once
Explanation:
Distance around the earth = circumference of earth = 2πR
[tex]Distance\ covered = 2*3.142*4000 = 25316\ miles\\\\Gallons\ of\ gas\ required = \frac{25316\ miles*1\ gallon}{25\ miles} =1005.4\ gallons\\\\Cost = \frac{1005.4\ gallon *3.20\ dollar}{1\ gallon} = 3217.28\ dollars[/tex]
