Question 1175404
Different animals have different fields of view.
 Humans can generally see a 180° arc in front of them.
 Horses can see a 215° arc.
 A horse and rider are in Baguio City which is experiencing heavy fog, so they can see for only 10 yards in any direction.
:
a. Find the area of the rider's field of view.
180 degrees means he can see an area that is a semicircle
A = {{{1/2}}}{{{pi*10^2}}}
A = 157 sq yds
:
b. Find the area of the horse's field of view.
Find the area of a circle with 10 yd radius
A = {{{pi*10^2}}}
A = 314.16 sq/yds
Find the area of a 215 degrees arc
A = {{{215/360}}} * 314.16
A = 187.6 sq/yds the area the horse can see
