40ft. All you have to do is multiply 5 feet by 8 inches since every inch equals 5 feet based on the scale.
<span><span>The sum of the degree measures of two complementary angles is 90, so subtract 18 from 90.

</span><span>The sum of the degree measures of two supplementary angles is 180...<span>

We know that
[area of a regular hexagon]=6*[area of one <span>equilateral triangle]
</span>210.44=6*[area of one equilateral triangle]
[area of one equilateral triangle]=210.44/6-----> 35.07 cm²
[area of one equilateral triangle]=b*h/2
h=7.794 cm
b=2*area/h------> b=2*35.07/7.794------>b= 9 cm
the length side of a regular hexagon is 9 cm
<span>applying the Pythagorean theorem
</span>r²=h²+(b/2)²------>r²=7.794²+(4.5)²------> r²=81--------> r=9 cm
<span>this last step was not necessary because the radius is equal to the hexagon side------> (remember the equilateral triangles)
</span>
the answer is
the radius is 9 cm
120 degrees or 0.67 radians
