height of d cone = 84m (given)
radius of it's base =35m (given )
by using Pythagoras formula,
slant height of d cone = 91m
therefore C. S. A of d cone = pi. r. l
= 22/7 x 35 x 91
=10010 sq m.....

since l=√r²+h²=√35²+84²=√8281=91
l=91m
csa of a cone =πrl=22/7*35*91 =22*5*91=10010m²
l=91m
csa of a cone =πrl=22/7*35*91 =22*5*91=10010m²
