a piece of paper is in the shape of a semi circular region of radius 10 cm. it is rolled to form a right circular cone. what is the slant height of cone?

pls give the solution.

Hi!
 
The slant height of the rolled right circular cone is the radius of the semicircular piece of paper. I.e., 10 cm
When the semicircular piece of paper is rolled to form a right circular cone, the circumference of the circular base of the right circular cone formed is the length of the curve part of semicircular piece of paper.
 
Best wishes!
