csa of cone = pi×r×l pi=22/7 r=14cm
77= 22/7×14×l
l= 77×7/22×2
= 7/4 77=11×7/22=11×2
cut 11
77= 22/7×14×l
l= 77×7/22×2
= 7/4 77=11×7/22=11×2
cut 11

after cut 11 then 2 × 2 = 4 in denominator
7/4=1.75cm so l= 1.75cm
nahi
kya nahi
formula age Alan hai
kya
pythagorus rule lsq=hsq+rsq so hsq=lsq-rsq
hsq=(1.75) sq-(14) sq = 3.0625-196
