Solution:
Given height of the cone, h = 24 cm
Radius, r = 7 cm
We know that l2 = h2+r2
l2 = 242+72
l2 = 576+49
l2 = 625
l = √625
l = 25
Curved surface area = rl
= (22/7)×7×25
= 22×25
= 550 cm2
So the area of the cloth required to make 10 such caps = 10×550 = 5500
Hence the area of the cloth required to make 10 caps is 5500 cm2.
