Cone 15

The radius of the base of a right circular cone is 14 inches and it's height 18 inches. What is the slant height?

Correct answer:

s =  22.8035 inch

Step-by-step explanation:

$$\begin{gathered} r=14\text{ inch } \\ h=18\text{ inch } \\ s=\sqrt{r^2+h^2}=\sqrt{14^2+18^2}=2\sqrt{130}=22.8035\text{ inch} \end{gathered}$$
