R = 16 according to the problem, so the total amount of income will be:
$20*16 + $15*(40 - 16)
= $320 + <span>$15*(24)
= </span>$320 + <span>$360
= $680
that is the income, but the expenses are $275 so the total revenue is the subtraction of those two
total revenue = $680 - $275
= $405</span>
Answer:
area = 3.44 in²
Step-by-step explanation:
area of square = 4 x 4 = 16 cm²
area of circle = (3.14)(2²) = 12.56 cm²
area = 16 - 12.56 = 3.44 in²
I'm assuming you are referring to the radius of a square
The first thing we have to do is divide by pi, because it's the last thing you do when calculating the area.
2289.06/3.14
729
Now, we have to take the square root of this number because the radius in the area formula is squared.
729^1/2
27
So, the radius is 27.
