Question

a cone of maximum size is carved out from a cube of edge 14cm .find the surface are of the cone ​

Answer 1

Answer:

996.31 cm^2

Step-by-step explanation:

For larger cone edge of cube = Height of cone = Diameter of base of cone = 14 cm

Let slant height be l cm.

Therefore h = 14 , r = 7

l ^2 = h^2 + r^2 ( Pythagoras theorem)

=> l = √245 ≈ 15.65

Therefore total surface area of cone = 2πr( l + r) = 2× π × 7 × 22.65 = 996.31 cm^2
