Answer:

5.25 miles

Step-by-step explanation:

We are required to determine the distance between Lighthouse A and Lighthouse B in the diagram.

Using Law of Cosines

$c^2=a^2+b^2-2abCosC\\c^2=7^2+4^2-2(7)(4)Cos48^\circ\\c^2=27.5287\\c=\sqrt{27.5287} \\c=5.25\: miles$

The distance between lighthouses is 5.25 miles.

The circumference is found by multiplying the radius by pi by 2

And then the arc length would be multiplied by the fraction of the circle..

So using what you wrote is correct, but the answer you got is incorrect.

2x 3.14 x 90 = 565.2 meters

565.2 x 90/360 = 141.3 meters
