1.	A9* A5. A circular dartboard is divided into four equalparts. What is the probability that a dart will landon the first part if all the darts land on the board?
Answer» 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%.

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)

=9π

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

Step-by-step explanation:
