Given :
A circle is inscribed in a square with a side length of 144.
So, radius of circle, r = 144/2 = 72 units.
To Find :
The probability that the point is inside the circle.
Solution :
Area of circle,

Area of square,

Now, probability is given by :

Therefore, the probability that the point is inside the circle is 0.785 .
Answer: D
Step by Step explanation:
The number relation that is between two amounts.
12x+2y=112
6x+y=56
6x=56-y
x=(56-y)/6
y=(56-6x)
24 hours in a day. 5 x 24 = 120 hours
