Question

Can someone please help me find the answer to the following

Answer 1

`14.4\pi ft^2`

Step-by-step explanation

The surface area of a cone is given as:

`SA=\pi\cdot r(r+l)`

where r = radius; l = slant height

From the question:

`\begin{gathered} r=2.4ft \\ l=3.6ft \end{gathered}`

Therefore, the surface area of the cone, in terms of pi, is:

`\begin{gathered} SA=\pi\cdot2.4(2.4+3.6) \\ SA=\pi\cdot2.4\cdot6 \\ SA=14.4\pi ft^2 \end{gathered}`
