Assuming the radius is 5.4m. The exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.
<h3>Length of an arc</h3>
Arc length of the circle=(theta)/360×pi×diameter
Diameter=2×radius
Where:
radius=5.4
Diameter=2×5.4=10.8
theta=60°
Arc length:
Arc length=60°/360°×π×10.8
Arc length=5.6548667765 or 1.8π
Inconclusion the exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.

Answer:
35.31mpg
Explanation:
From the question given, the efficiency of the fuel in L/100km is given by: 8L/100km.
The efficiency of the fuel in miles per gallon can be obtained as follow:
1L/100km is equivalent to 282.481mpg.
To obtain 8L/100km in miles per gallon, we simply divide 282.481 by 8L/100km as shown below:
8L/100km in mpg = (282.481)/(8L/100km) = 35.31mpg
Therefore, the efficiency of the fuel in miles per gallon is 35.31mpg
