Answer 1

Answer:

The width of the window should be $7.6\ ft$ and the height of the window should be $3.8\ ft$

Step-by-step explanation:

we know that

The circumference of a semicircle (window) is equal to

$C=\pi r$

we have that

$C=12\ ft$

$\pi=3.14$

substitute and solve for r

$12=(3.14)r$

$r=12/3.14=3.8\ ft$

so

the width of the window is equal to the diameter of the semicircle

so

The width of the window should be $3.8*2=7.6\ ft$ and the height of the window should be $3.8\ ft$
