Question

2. If the slant height and the vertical height of a cone
are 5 cm and 4 cm respectively, then the volume
of the cone is
(a) 12π cm3
(b) 13π cm3
(C) 14π cm3
(d) 15π cm3​

Answer 1

Answer:

a 12π cm3

Step-by-step explanation:

slant height=5 cm

vertical height=4 cm

so,l^2=r^2+h^2

5^2=r^2+4^2

r=3

volume=1/3πr^2h

=1/3×π×3×3×4

=12π cm^2
