Problema Solution
a lighthouse's beacon reaches a distance of 8 miles with a 180 degree rotation. find the square mileage covered by the light house
Answer provided by our tutors
R = 8 mi
A = the area of the coverage
A = R^2*pi(180/360)
A = 8^2*pi*(1/2)
A = 32 pi mi^2
pi = 3.14
A = 32*3.14
A = 100.48 mi^2
The square millage covered by the lighthouse is 100.48 mi^2.
