Answer:
c) 20
Step-by-step explanation:
Area of hexagon = (3√3)/2 x a²
= (3√3)/2 x 100
= 259.81
It means the area of circle must be lesser than 259.81
=> Area of circle = πr²
=> πr² < 259.81
=> r² < 259.81/π
=> r² < 193.88
=> r < 13.9 => d < 27.8
Therefore, nearest value for the diameter given in the options is 20....
So we assume that the diameter of the circle must be 20...
I hope you get it!
