Question

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

Answer 1

Area of cone=3.14*9+3*6*3.14=27*3.14


=84.78 cm^2 if we cut into four identical pieces we get two triangle surfaces also for 1 piece and and 1/4 of the original surface area =21.195+15.588=36.783squarecm
