Answer:
π
Step-by-step explanation:
Formula for the circumference of a circle
2r(π)
Area of a circle
πr²
2r(π)=x
x/2(π)=r
π(x/2(π))²=Area
π(x²/4(π)²)=Area
(x²/4(π))=Area
(15π)²÷4π=Area
π
(B)
if <em>f</em>(a) = K, then that means <em>f </em>sends (a) to (K).
the inverse function, <em>f</em>-1, goes back where you started, so <em>f</em>-1 <em />sends (K) to (a).
<em>f</em>-1(K) = a.

Answer:
0.6708 or 67.08%
Step-by-step explanation:
Helen can only make both free throws if she makes the first. The probability that she makes the first free throw is P(C) = 0.78, now given that she has already made the first one, the probability that she makes the second is P(D|C) = 0.86. Therefore, the probability of Helen making both free throws is:

There is a 0.6708 probability that Helen makes both free throws.
