Answer:
The perimeter of the regular octagon is 104 units
Step-by-step explanation:
we know that
The segment LM is the length of one side of the octagon
we have the coordinates
L(-6,-2) and M(6,3)
step 1
Find the distance LM
the formula to calculate the distance between two points is equal to

substitute the values




step 2
Find the perimeter
we know that
A regular octagon has eight equal sides
so
To find out the perimeter, multiply by 8 the length of the segment LM

Because the formula for the area of a rectangle is length times width, all you have to do is multiply 15 by 15 and it should get you 225 as your answer
Answer:
B
Step-by-step explanation:
area of the full piece of pie. π(8)²*60/360 (we know 60°, because it's an equilateral triangle)
32π/3
now subtract the area of the triangle
1/2(8)(4√3) = 16√3
32π/3 - 16√3
