Find the probability
To do this, let's find the area of the triangle and the circle.
32(1/2) = 16
Area = 16pi
Probability: 16/16pi = 1/pi
ilorty: How many triangles are there and what is their combined area?
oops, I did not see that! Silly me...
The red triangle has area (1/2)*8*4 = 16 cm2.
The circle has area pi*42 = 16pi cm2
Hence probability that oint lis in red triangle = 16/(16pi) = 1/pi;
