Square ABCD has side length a. Half circles with

Inga [223]

The area of the shaded region is $0.215a^2$

<h2>Area of composite objects</h2>

The area of the shaded region is expressed according to the formula:

$A = A_s - A_c$

Get the area of the square As

As = a²

$A_c = \pi (0.5a)^2\\
A_c = 0.785a^2$

Take the difference in the areas

Area of the shaded part = $a^2-0.785a^2\\
$

Area of the shaded part = $0.215a^2$

Hence the area of the shaded region is $0.215a^2$

a business owner pays $500 a week for rent.He also pays an employee $16 an hour.If his total weekly expenses are $1,172 ,how man

Ganezh [65]

42 hours

EXPLANATION:

To find the answer, we should start with the total and get rid of the amounts that we know.

So we know the total is 1,172 in a week, and that 500 dollars of it is for rent.

1,172 - 500 =672.

Now we have 672 left.

We know that it was all spent on employees.

we know it is $16 for each hour.

672 divided by 16 is 42 total hours.

Hope this helps!
