Answer:
The width of the window should be [tex]7.6\ ft[/tex] and the height of the window should be [tex]3.8\ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a semicircle (window) is equal to
[tex]C=\pi r[/tex]
we have that
[tex]C=12\ ft[/tex]
[tex]\pi=3.14[/tex]
substitute and solve for r
[tex]12=(3.14)r[/tex]
[tex]r=12/3.14=3.8\ ft[/tex]
so
the width of the window is equal to the diameter of the semicircle
so
The width of the window should be [tex]3.8*2=7.6\ ft[/tex] and the height of the window should be [tex]3.8\ ft[/tex]
