darnells's car used 8 gallons of gasoline to travel 340 miles.After a mechanic worked on the car it used 7 gallons of gasoline t
o travel 350 miles. If the price of the gasoline was approximately $4.00 a gallon,to the nearest cent per mile,did it cost to run the car after the mechanic worked on it
If it is $4.00 per gallon then we need to find the price of 7 gallons. 7 * 4.00 = 28 so it costs $28 to travel 350 miles. no to find the cost per mile, we need to divide. 350 / 28 = 12.5 so the cost to run the car per mile is $12.50
You divide 125.6 by 3.14 which = 68.66 That's the diameter. so the nearest cm is 69cm The radius is half of the diameter so to the nearest cm it is 34cm
