curved surface area of the cone=πrl
=3.14×12×20
=753.60sq.cm
total surface area of cone =πr(l+r) =3.14×12(20+12)=1205.76sq.cm
=3.14×12×20
=753.60sq.cm
total surface area of cone =πr(l+r) =3.14×12(20+12)=1205.76sq.cm
it's correct
hmm
but Yaha given nhi h ki π ki value 3.14 Leni h
to Aap Apne mn s kse L rahi ho
agar given nahi he to hum apne man se value le sakte hai
pai ki
Kyu agar ham 22/7 Le to
ha le sakte hai
