Question

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

Answer 1

Answer:

  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
