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

Radius of the shaded region = 2 in
Area of shaded region is given by

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

Hence, the required probability is 0.25.
I assume that it’s an equation so:
2x^3-4=0
x=(2)^(1/3)
The answer is in the image hope this helps
C=2x Pi x R so 2x3.14x17.5 = 109.9
