Step-by-step explanation:
added up all of the numbers for each face
hope this helps!
N=30°. The sum of the angles is 180º. n+n+4n=6n, so 6n=180 and n=30°.
n=18°. 4n+n=90, so 5n=90, n=18°.

Answer: 9/38</h3>
Reason:
There are 10 red cards out of 10+10 = 20 total.
10/20 = 1/2 is the probability of selecting a red card.
If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19
Multiply the two fractions mentioned to get the final answer.
(1/2)*(9/19) = (1*9)/(2*19) = 9/38
Answer: C: 2787.64
Explanation: The height of the cone equals 22, the diameter of the circle is 22, divide it by 2 to get the radius which is 11. Then plug in data into formula: V=
