Can you just me with 1 of the figures in my math problem and explain how you got it

part 1: polygons and circles

a. dakota with her homework. use diagrams of inscribed polygons to approximate the area of each circle. assume that all of the circles have a radius of 1.
the attachment isn't working so i to try to describe it as best as i can:
the inscribed polygon is a triangular shape b=1.73 and h= 0.5

  area of triangle: 1.2975

  area of circle: π ≈ 3.1416

Step-by-step explanation:

The side length (B) is used to compute the perimeter of the triangle. For the 3-sided triangle, the perimeter is ...

  P = 3B = 3·1.73 = 5.19

The "height" (H) measured from the center of the circle to the middle of one side is called the "apothem" (a). The area of the triangle (A) is the product of half that and the perimeter:

  A = (1/2)aP = (1/2)·0.5·5.19 = 1.2975 . . . . . . square units

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
