Answers
Given : A triangle inside Circle
To find : probability that a randomly selected point within the circle falls in the white area.
Solution:
Area of Circle = πr²
r = 4 cm
π = 3.14
Area of Circle = 3.14 * 4² = 50.24 cm²
Area of Triangle = (1/2) (3 + 3) * (4 + 2.5) = 19.5 cm²
White ares is not clear
Probability of falling in Triangle = 19.5/50.4 = 0.39
Probability of falling outside Triangle in Circle = 1 -0.39 = 0.61
However Data is not very correct
at radius from 2.5 cm & 3cm Data comes out to be 3.91 cm instead of 4 cm
