"a magician performing a magic act has asked for 2 volunteers from the audience to with his routine. if there are 250 people in the audience, which of the following expressions represents the number of possible pairs of volunteers? "

Number of people in the audience = 250

     Number of volunteers required to perform the magic act from the audience =2

As 2 people can be selected from 250 people by using the properties of combination as order of choosing people is not important.

Possible number of ways =

                      =

                      = 31125 ways

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
