Answer:
2727
Step-by-step explanation:
The formula for finding the volume of a cone is
1/3πr²h
The radius would be 11.5 because, radius equals the diameter divided by two.
So, first you would plug your numbers into the equation
1/3(π)(11.5)²(19.7)
*use 3.14 for pi
Then multiply.
V = 2726.9 (2727 if you round to the nearest whole number)
Answer:
422.39
Step-by-step explanation:
![A = \pi r^2\\A = 144\pi \\\\144\pi -30 = 422.39](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2%5C%5CA%20%3D%20144%5Cpi%20%5C%5C%5C%5C144%5Cpi%20-30%20%3D%20422.39)

Answer:
Step-by-step explanation:
5x2=10 3x4=12 2x2=4 6x1=6
The events
are independent if and only if
. Under this condition, we have conditional probabilities
![P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{P(A)\cdot P(B)}{P(B)}=P(A)](https://tex.z-dn.net/?f=P%28A%5Cmid%20B%29%3D%5Cdfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D%3D%5Cdfrac%7BP%28A%29%5Ccdot%20P%28B%29%7D%7BP%28B%29%7D%3DP%28A%29)
![P(B\mid A)=P(B)](https://tex.z-dn.net/?f=P%28B%5Cmid%20A%29%3DP%28B%29)
so the answer is D.
