The radius of the earth is about 4,000 miles. if there were a global superhighway that circles around the entire equator of the earth, approximately how much would it cost for you to buy enough gas to drive around the earth once? assume that the gas costs $3.20 a gallon and that your car can get 25 miles per gallon.

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

radiation

explanation:

heat is transmitted by radiation

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
