Question

Hello, I really help on need question 2 for geometry

Answer 1

Given:

Given that a cone with

`\begin{gathered} r=7.2m \\ l=17m \end{gathered}`

Required:

To find the surface area of the given figure.

Step-by-step explanation:

The formula for surface area of cone is

`SA=\pi r^2+\pi rl`

Where r = radius

l = length.

Now,

`\begin{gathered} SA=\pi(7.2)^2+\pi*7.2*17 \\ =51.84\pi+122.4\pi \\ =174.24\pi \\ =547.1136m^2 \end{gathered}`

Final Answer:

The surface area of the given figure is 547.11 square meter.
