Answer:
area of this circle: 490.6 inch²
Step-by-step explanation:
area of circle: π(radius)²
Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in
using the formula:
3.14(12.5)²
490.625 inch²
490.6 inch²____rounded to nearest tenth.
the question in English
50 t-shirts were sold at 10€ each. What benefit was obtained if the t-shirts were bought at 7€ each?
Let
x---------> the benefit in euros
we know that
therefore
<u>the answer is</u>
The benefit is equal to 
Side of the square: s
Area of the square: As=s^2
Diameter of the circle: d=s
Area of the circle: Ac=pi d^2/4
Ac=pi s^2/4; pi=3.1416
Ac=3.1416 s^2/4
Ac=0.7854 s^2
<span>The likelihood that a point chosen inside the square will also be inside the circle: P=?
P=Ac/As=0.7854 s^2 / s^2
P=0.7854
P=0.7854 * 100%
P=78.54%
</span>The likelihood that a point chosen inside the square will also be inside the circle is 0.7854 or 78.54%
