Question

A circle of radius 0.7 cm is inscibed in triangle ABC, if a dart is thrown to this figure, find the probability of the dart hitting the interior of triangle except the area of circle​

Answer 1

Answer:

In given radius of area C is 1,B is 2 and A is 3.

Then total area of circular region with radius 3 cm = π(3)

2

=9π

The area of circular region with radius 2 cm = π(2)

2

=4π

Then heating area of region A= 9π−4π=5π

Then probability of a dart hitting board region A=

total area of circular disc

area of region A

=

9π

5π

=0.55

Then probability of a dart hitting board region A=55%.
