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

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
