Question

A cone of radius 3 cm and slant height 6cm is cut into four identical pieces. Calculate the total surface area of the four pieces.

Answer 1

Total surface area of the pieces = surface area of cone..

Answer 2

base area = PI *r*r
surface area = PI*r*s
PI = 22/7
r= 3 cm
S = 6 cm
Total area = base area + surface area
area of each piece = total area / 4

Answer 3

I forgot to add the inside area
add inside area also for each piece = 1/2 * base* height

Answer 4

Is it a solid cone....?

Answer 5

Its not written in the question

Answer 6

When it's a solid cone it's surface area = area of four pieces
