Anita made a wax model of a rolling pin of diameter 6 cm. The rolling pin was shaped like a right circular cylinder with a right circular cone at each end as shown below.
A rolling pin shaped as a cylinder with conical ends. The length of the cylindrical part is 9 cm, the slant height of each cone is 4 cm and the diameter of the rolling pin is 6 cm.

anonymous · Answer

surface area of all 3 shapes - 4 times the area of the 6cm diameter circle they share

anonymous · Answer

what are the steps you used to find that?

anonymous · Answer

@Euler271

anonymous · Answer

just logic. the SA of the outside of the shapes are their natural surface areas minus their circular end area

anonymous · Answer

but i have to answer it in paragraph form @Euler271
