Question

A cake decorator rolls a piece of stiff paper to form a cone. She cuts off the tip of the cone and uses it as a funnel to pour decorative sprinkles into small containers. The cone has a radius of 666 cm and a height of 181818 cm.

Answer 1

Area of cone = πr(r+√h²+r²)

= 22/7 × 666cm( 666cm + √666cm² + 181818cm²)

= 22/7 × 666cm(666cm + 666cm + 181818cm)

= 22/7 × 666cm × 183,150cm

= 22/7 × 121977900cm²

=
