Answer:
The probability of the dart hitting the inner circle is 11.2 %.
Step-by-step explanation:
To solve this problem we first need to find the area of the whole target and the area of the smaller target. Since they're both circular, their area is given by the formula:
area = pi*r²
For the whole target:
area target = pi*(6/2)² = 28.26 ft²
For the inner target:
area inner = pi*(2/2)² = 3.14 ft²
The probability that the dart will hit the inner area is:
p = area inner / area target = 3.14 / 28.26 = 0.112
The probability of the dart hitting the inner circle is 11.2 %.
This is a little long for one question. I can see that 2 is CPCTE, and 1 is probably Given. 3 might be interior angles are equal.
