yes.it has to be converted into a square root equation though which is where im stumped.

Answer 6

Just a second...

Answer 7

ok

Answer 8

yes it did i have to go thanks for the help

Answer 9

((sqrt(3))/(4))*6^(2)

Squaring a number is the same as multiplying the number by itself (6*6).
((sqrt(3))/(4))*6*6

Multiply 6 by 6 to get 36.
((sqrt(3))/(4))*36

Multiply ((sqrt(3))/(4)) by 36 to get 36((sqrt(3))/(4)).
36((sqrt(3))/(4))

Multiply 36 by the (sqrt(3))/(4) inside the parentheses.
36*(sqrt(3))/(4)

Remove the common factor of 4 from the numerator of the first expression and denominator of the second expression.
9*sqrt(3)

Multiply 9 by sqrt(3) to get 9 sqrt(3).
9 sqrt(3)

9 * 1.7320508075688772935274463415059 = 15.588457268119895641747017073553

Round it:
15.59 in^2

I don't know if that helped.
