Question

he radius and slant height of Cone is 2 cm and 6cm respectively its curved surface

area is ……….........cm².​

Answer 1

Answer:

curved surface of cone=pie × r × l

=3.14×2×6 =3.14×12=37.68cm^2

Answer 2

Answer:

by Pythagoras theorem

l²=r²+h²

(6)²=(2)²+h²

36=4+h²

h²=36-4

h²=32

h=4√2 cm

area of cone = πr(r+l)

=22/7×2(2+6)

=44/7×8

=352/7

=50.28cm²
