Find the area of the shaded region, round to two decimals​

A = 660.72 in^2 - A = 98 in^2 = 562.7 in^2

Step-by-step explanation:

Formula for a seven sided polygon/heptagon is:

A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n

nn = 7 sides

side lengtha = 13.4841 in

inradiusr = 14 in

circumradiusR = 15.5388 in

areaA = 660.72 in^2

perimeterP = 94.3886 in

interior anglex = 128.571 °

exterior angley = 51.4286 °

To calculate the square from a diameter use this formula: q = √(2a^2) = a√2

side lengtha = 9.8994949366117 in

diagonalq = 14 in

perimeterP = 39.597979746447 in

areaA = 98 in^2

question:

could we have options?

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
