If the arc on a particular circle has an arc length of 14 inches, and the circumference of the circle is 84 inches, what is the angle measure of the arc?
60°
90°
120°
180°

the arc length is 14 and circumference is 84

so it is 14/84 of the circle. 14/84 can reduce to 1/6

a circle has 306 degrees

 now multiply 360 x 1/6  = 60 degrees which is the angle measure

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
