Assume that the radius of the circle is 1.


The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).


Finally, the ratio of the square to the circle, in area, will be


(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi


We can conclude that the white area is about 35%.

PLEASE HELP IVE POSTED THIS AND NO RESPONSE YET ! It’s an exam

Answer: 262,000? I'm just guessing

Step-by-step explanation:

one product costs $14 to produce. It is mentioned that you need to produce 14,000 products or items, so you multiply 14 by 14,000 to know the total cost of producing 14,000 items or products, the answer is 196,000, remember there is also a start-up cost of 66,000. So you must add 196,000 to 66,000 which leads to 262,000. Hope this helps :)

Find the missing side of the triangle. leave your answer in simplest radical form
KIM [24]

missing side is x} = 10.15 mi .

<u>Step-by-step explanation:</u>

Here we have the following info from the figure: A right angled triangle with following dimensions

Perpendicular = x

base = \sqrt{122}

Hypotenuse = 15

By Pythagoras Theorem :

Hypotenuse^2 = Perpendicular^2 + base^2

⇒ Hypotenuse^2 = Perpendicular^2 + base^2

⇒ 15^2 = x^2 + (\sqrt{122})^2

⇒ 225 = x^2 + 122

⇒ x^2 = 225-122

⇒ x^2 = 103

⇒ (x^2)^\frac{1}{2} = (103)^\frac{1}{2}

⇒ x} = (103)^\frac{1}{2}

⇒ x} = 10.15

Therefore, missing side is x} = 10.15 mi .
