Total surface area of a sharped pencil ? ​

Answer 1

To find the answer, more information is needed.

Answer 2

Answer:

The volume of a cylinder with radius rr and height hh is πr2hπr2h. The volume of a right circular cone with base radius rr and height xx is 13πr2x13πr2x.

Then, the total volume of the pencil is πr2h+13πr2x+13πr2y=πr2(h+x+y3)πr2h+13πr2x+13πr2y=πr2(h+x+y3).

Note that x+y=110−hx+y=110−h and simplify.
