Question

Find the area of the metal sheet required to make the closed Hallow cones each height is 24 cm and slant height is 25 cm

Answer 1

Answer:

answer is 550 square cm

Step-by-step explanation:

given,

h=24cm

l=25cm

r=?

so,

l^2=h^2+r^2

25^2=24^2+r^2

625=576+r^2

r^2=625-576

r=square root of 49

r= 7

r=7cm

now ,we have to find curved surface area of cone

then

csa of cone =pi× r×l

=22/7×7×25

=22×25

=550

therefore, the area of metal sheet required to make hollow cone=550cm.sq
