I think it depends on the depends on what result you are looking for if it is the exponential model used in the problem. In this problem, it does show how someone gets this results. Both the exponential growth and decay can be used in exponential functions.

If the base is greater than 1, then you have a case of exponential growth.

Find the probability that the dart lands in the shaded circular region. The radius of the dartboard is 4 in, and the radius of t

PilotLPTM [1.2K]

Answer: The required probability is 0.25.

Step-by-step explanation:

Since we have given that

Radius of the dartboard = 4 in

Area of the dartboard is given by

$\pi r^2=3.14\times (4)^2=3.14\times 16=50.24\ in^2$

Radius of the shaded region = 2 in

Area of shaded region is given by

$\pi r^2=3.14\times (2)^2=12.56\ in^2$

So, the probability that the dart lands in the shaded circular region is given by

$\dfrac{12.56}{50.24}=0.25$

Hence, the required probability is 0.25.
