Answered by avni1101

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

Krishna11123: it's correct

avni1101: hmm

rrRitikgupta1231: but Yaha given nhi h ki π ki value 3.14 Leni h

rrRitikgupta1231: to Aap Apne mn s kse L rahi ho

avni1101: agar given nahi he to hum apne man se value le sakte hai

avni1101: pai ki
