Answer:
900
Step-by-step explanation:
V=πr2h
3.14 x 11= 34.54
34.54 x 2= 69.08
69.08x 13= 898.04
898.04 rounded to nearest hundreth is 900
Housing + Food + Transportation= 1,168
1,600 - 1,168= 432 left.
Using the PSN method:
P = -9
S = 8
So N = 9,-1
Using 9 and -1 in the original equation gives:
1.
Consider a group of n objects. Assume we want to form groups of r, from these n objects.
There are in total

many ways of doing so.
where, r! is "r factorial", calculated as 1*2*3*...*(r-1)*r
2.
C(x, 2) is the total number of pairs out of x objects, that we can form.
so let the x objects represent the x teams, and 2, represent a group of 2, which means a game.
The total number of games is:
n(x)=2*C(x, 2) =

Remark, we multiplied by 2, since there will be 2 matches for each pair of teams.
