If you were buying an item at the store for 61 Dollars and there is a 6.7 tax added on top of it with the total due at the register

65.09

Step-by-step explanation:

61×6.7%＝4.087

4.087+61＝65.087

65.087≈65.09

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 function makes a strait line horizontally with no x intercept but a y intercept at 9.
