square root(-108) - square root(-3) =8.66025404 i
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

Step-by-step explanation:
x < 12
Answer:
3^10
Step-by-step explanation:
Because the rules of index
3^4 = 3*3*3*3
3^6 = 3*3*3*3*3*3
(3^4)(3^6)=
3*3*3*3*3*3*3*3*3*3 = 3^10
