ans is 6.243 inner hexagon side =3 then second 8 third 13 .......... so series wou;d be like 3,8,13............98 sum =20/2(2*3 +19*5)=6060 now diadonal would be twicw the side lenhth .......ie for side 3mm diagonal is 6mm so last diagonal would be of lnght=(19*5+3)*2*3=196*3=588 so total =6060+588=6648mm

a spider web consists of 3 concurrent lines forming radial support for 20 concentric regular hexagon .the hexagon vertices are 5mm from their immidiate neighbour. if the innermost hexagon has a side length 3mm how many meters is the length of the entire web including the 3 diagonals ?

There are 20 concentric hexagon starting length from 3 and next is 5 more than previous i.e;
3,8,13,18.........98 total 20terms

Sn=20/2(3+98)=1010

becz hehagon has 6 sides so total lenght=1010*6=6060

And now calculate three concurrent line which are radii of hexagon

we know that radii =2*length of hexagon

but the concurrent line is lenth b/w the vertices of hexagon

so length=2*side*2

= 2*98*2=392

for three lines=392*2=784


now total length =6060+784=6844 mm (ANS)
