Question

Find the area of iron sheet required to prepare cone 24cm height with base radius 7cm

Answer 1

Answer:

Step-by-step explanation:

We need to find csa of the cone to find the total sheet required

Given height of cone = 24cm

Given base radius = 7 cm

Now we need to find the slant height

slant height l = square root of h^2 + r^2

=square root of 24^2 +7^2

=square root of 576+49

=square root of 625

= 25

Therefore slant height = 25

csa = pi*r*l

=22/7*7*25

=22*25

=550 sq. cm
