A lighthouse casts a revolving beam of light as far as the pier. What
is the area that the light covers?

We have that The area that the light covers is  is mathematically given as

From the Question we are told that

Revolving beam of light as far as the pier

Let distance to pier be x

Generally the revolving beam turns a complete angle of 360

Therefore

Its goes in a circle

The area that the light covers is  is mathematically given as

In conclusion

The area that the light covers is  is mathematically given as

First, let's find how far away the pier is.

Using the distance formula, we can see that the pier is units away.

So, the radius is sqrt 58.

Area = pi (r)^2

So,  the area is 182.82 square units.
