hexagon with radius 5 in.
A) 259.8 in2
B) 129.9 in2
C) 65.0 in2
D) 53.0 in2

Thanks!

Answer 1

apply the formula (x-2) x180 to find the interior angle. x is no. of sides. answer = 720 deg
divide the hexagon into six triangles each with interior angle 120 deg
apply 1/2 (5) (5) sin 120 to find the area of 1 triangle
multiply the answer with 6 to get the area of hexagon

Answer 2

i think I did it wrong lolz

Answer 3

1/2 x 25 sin 120 = 10.83 in
10.83 in x 6 = 64.95 = 65 in ^2
