Pi*r^2
3.14*7000^2
153,860,000
Answer:
72
Step-by-step explanation:
3(20+4)=a0
60+12=a0
72=a0
im not quite sure what you want. I solved for a0. Plz tell me if this is correct. If its not, tell me what u need, then I will solve it for you.
Answer:

Step-by-step explanation:
You can do this using the quadratic equation:

Let's first setup our expression:
4x² + 12x = 135
the quadratic formula is:
ax² + bx + c = 0
4x² + 12x - 135 = 0
Then:
a = 4
b = 12
c = -135
Now we plug in our coefficients and solve:

We solve for both to determine the positive one:





So if you are looking for a positive solution, just take the positive one as x.
Explanation:
There may be a couple of reasons for this:
1. Each team represents a sample of the players in the league. The averages of (random) samples can be expected to have a standard deviation that is smaller than the population standard deviation by a factor related to sample size.
2. A team average will result from the players who are played the most. Each team can be expected to field players more often whose averages are among the highest. The standard deviation of a set of the top tier of players will necessarily be smaller than the standard deviation of the set of all players.
