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 .
OPTION A , C,D
are the correct choices because all of them are equal to √5
We have an inscribed angle here. Angle YXZ is an inscribed angle.
Angle YXZ can also be expressed as simply angle x but I will use angle YXZ.
Angle YXZ = (1/2)(arc YZ)
Angle YXZ = (1/2)(144°)
Angle YXZ = 72°
Done!
$70 into 1:2:4
1+2+4 = 7
7 parts= $70
1 part = $70/7 ($70 divided by 7)
1:2:4 = $10:$20:$40
answer= $10:$20:$40
Hope this helps!! :)
