Answer:</h2>
C = 2πr
r = C/2π ...(1)
A = πr²
A = π(C/2π)² = πC²/4π²
A = C²/4π.
<u>Correct choice</u> - [A] A = C²/4π.
Okay the way to do this: Find the probability of the first event and then the probability of the second event. Then, multiply the probabilities. So:
(7/13)*(6/12)
So the answer is about .27 or 27%
The answer is true and true
