I used 3,14 for pi since it was only way it made sense based on the answers.
The question probably provided you with this.
If you have any more questions do not hesitate :)
The probability that a point picked at random in the square is in the shaded region will be 86/314. Thus option C is correct.
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
Given:
A circle with a diameter of 20 m is inscribed in a square .
Thus side of square = 20 m
Now, area of square = 20 x 20
= 400 sq m
The radius of circle = 10 m
Area of circle
[tex]A = \pi r^2\\\\A = 3.14 \times 10^2\\\\A = 314 m^2[/tex]
Now, Area of shaded region = Area of the square - an area of circle
Area of shaded region = 400 - 314
= 86
The probability that a point picked at random in the square is in the shaded region will be 86/314. Thus option C is correct.
