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 ? Choose the most appropriate option.
A) 6.1	B) 6.3	C) 7.2	D) 8.2	E) 9.2
for perimeter of all hexagon =6*(3+8+13+...........20th term.)   sum will be 6060 mm   and for length of one diagonal find 20th term=98   so total length =6060+294=
