What is the lateral and surface area of a cone with a diameter of 6 inches and a slant of 5 inches?

Question

A cone with a diameter of 6 inches and slant of 5 inches.

Answer 1

The formula for the lateral surface area of a right cone is L . S . A. = pi•l•r, where l is the slant height of the cone. 

 

The formula for the total surface area of a right cone is T . S . A.= pi•r•l + pi•r²

 

NOTE:I spelled out "pi" because the symbol when inserted too often looks like n
