Divide the hexagon into 6 equal streak triangles which would have side length equal to the radius of the circle.
the area of an equal lateral triangle = sqrt(3)/4 x radius^2
the area of the hexagon would be 6 x sqrt(3)/4 x radius^2
Area = 6 x sqrt(3)/4 x 8^2 = 166.2768 square feet
rounded to the nearest whole foot = 166 square feet.
First, "the sum of a number and four" is x+4.
Three times (x+4) is 3(x+4). It's also the left side of the equation.
Second, "five times the number" is 5x.
The result will then be "decreased by two", which is 5x-2. It's also the right side of the equation.
Therefore, option (1) is the correct answer.
Hope this would help :))
127.17 because 9x9=81 and 81x3.14=254.34 then divide by 2 and it’s equal 127.17
Answer:
256.
Step-by-step explanation:
1 × 4 = 4
4 × 4 = 16
16 × 4 = 64
64 × 4 = 256
50 you don't need to do anything else it already is approximate
