6.6 +11.2=17.8
17.8-2=17.6

Curved surface area of corn=πrl.
Now,I=√{(r(sq)+{(h(sp)}
=√{6.6(sq)+ 11.2(sq)
=√(43.56 +125.44)
=√169= 13cm
So,curved surface area =22/7×6.6*×13cm(sq)
=269.7cm(sq)
Now ,when 1cm (sq) covers=2 kernels
then 269.7cm (sq) will cover=269.7×2=539.4 kernels....
Hence, 539 kernels (approx) will be in the corn.........
