given,
height,h=84cm
radius,r=350m
=35000cm
slant height,l=√h^2+r^2 (root under h^2+r^2)
=√84^2+35000^2 cm
=11180cm
curved surface area=πrl
= 22/7*35000*11180 cm^2
= 1229800000cm^2 (ans)

C.S.A= π×r×l where l is slant height
h= 84cm
r=350m = 35000cm
C.S.A= πrl
=22/7×35000×84
=22×5000×84 (7&35000 are
divided)
=110000×84
=9240000cm sq.
=9240000/10000 m sq.
= 924m sq.
h= 84cm
r=350m = 35000cm
C.S.A= πrl
=22/7×35000×84
=22×5000×84 (7&35000 are
divided)
=110000×84
=9240000cm sq.
=9240000/10000 m sq.
= 924m sq.
h means not slant hight
i have not meant h to be the slant height . Moreover the value you gave is an odd one so please check the question.
