An automobile engine consumes fuel at a rate of 18 L/h and delivers 58.2 kW of power to the wheels. If the fuel has a heating value of 42,756 kJ/kg and a density of 0.951 g/cm3, determine the efficiency of this engine in percentage. (Write your answer using 3 decimal places.)

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
