Answer:
Step-by-step explanation:
By definition:
The pre-meter P of a triangle ABC is equal to the sum of the length of its sides.
We know that:
The perimeter is:
Now we find the length of the sides:
Once the length of the sides is known, we use Heron's formula to calculate the area.
First I find the semiperimeter S.
Then the Area is:

Divide the hexagon into 6 equal streak triangles which would have side length equal to the radius of the circle.
the area of an equal lateral triangle = sqrt(3)/4 x radius^2
the area of the hexagon would be 6 x sqrt(3)/4 x radius^2
Area = 6 x sqrt(3)/4 x 8^2 = 166.2768 square feet
rounded to the nearest whole foot = 166 square feet.
Given: 3.2*10^2-8.7*10^6
Exponents: 3.2*100-8.7*1000000
Multiply: 320-8700000
Subtract: -8699680
