HELP PLS!! INCLUDE EXPLAINING THANK YOU

Lucy paid the least amount of money and she paid $770

Step-by-step explanation:

The way to find dylans is

1000-80= $920

920 x .15= $782

for lucy you do:

1000 x .15= $150

150 + 80= $230

1000-230= $770

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

it could be 1,3 and more others to create a cylinder.
