Question

A solid cylinder of height 21 cm and radius of base 56 cm is
melted and recast into a circular cone of height 3 times that of
the cylinder. Find the area of the curved surface of the cone.​

Answer 1

Cone CSA=22divided by 7×radius ×slant height

Step-by-step explanation:

height=21cm

height of come =21×3=63cm

radius=56cm

l^2=root r^2+h^2

56^2+63^2

3136+3969=7105

root of 7105=84.29

22divided by 7×56×84.29=14835.04cm^2
