Question

THE RADIUS OF A CYLINDER IS 14CM AND HEIGHT IS 7CM .IF IT IS MELTED, ,FROM THIS HOW MANY CONES OF RADIUS 3.5 CM AND HEIGHT ALSO 3.5 CM CAN BE PREPARED

Answer 1

r=14 cm
h=7 cm
v=$\pi *14 ^{2} *7=4312 cm ^{3}$
r=3.5
h=3.5
v=[tex] \frac{1}{3} \pi r^{2} h \\ \frac{1}{3} *42.875*22/7=44.91 cm ^{3} [/tex]
number of cones=$\frac{4312}{44.91} =96.01$
we can make 96 cones

Answer 2

Volume of cylinder:
r=14 cm
h=7 cm
v of cylinder = π r² h =22/7 * 14² * 7
=4312 cm³

Volume of cone
r=3.5
h=3.5
v=1/3 π r² h = 1/3 * 22/7 * 3.5² * 3.5 = 44.91 cm³

Number of cones=$\frac{V of cylinder}{V of cone}$
= 4312/44.91
=96 Cones
