2 A hexagon has the weird property of having the radius and the side being of exactly the same length
The formula is A = 3 * sqrt(3) * a^2 / 2 where a = the side or radius A = 3 * sqrt(3) * 5^2 / 2 A = 3 * sqrt(3) * 25 / 2 A = 1.5 * sqrt(3) * 25 A = 64.95
A <<<< Answer (the first one is the answer.)
C This one seems so much more entailed. Do you know what the cos law is? That's what I will use to find c.
c^2 = a^2 + b^2 - 2*ab* cos(C) C = 33 degrees a = 2.75 miles b = 1.32 miles
Now you have to use this result to get the area. You have to use Heron's formula.
A = sqrt(s * (s - a) * (s - b) * (s - c) ) s = 1/2 the perimeter s = 1/2 (2.75 + 1.32 + 1.7934) s = 1/2(5.8634) s = 2.9317 I'll finish this in the comments. I have to leave for a bit.
