A store manager receives hourly updates about the sales in cash registers throughout the store. The stem-and-leaf display below shows the sales from the
most recent hour. What is the median sale?
10 5 5 8
11 257
12 1 4 7 8
14 3 3 4 5 7
15 1 2 48
16 0
18 2 3 9
20 3

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

the answer is y = 11.54

hope this : )
