Adisc jockey wants to select 4 songs from a new cd that contains 12 songs. how many ways can the disc jockey choose four songs?

I suppose a DJ wants to select 4 different songs, then there are: 12*11*10*9 = 11880 ways to choose them.

If the order of the songs he plays doesn't matter, there are: ways to choose them.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
