Question

Find the surface area.

Answer 1

`SA=106.46cm^2`

Explanation:

We will have to use the formula to find the surface area of a cone, which is:

`SA=\pi r(r+√(h^2+r^2))`

Dimensions of the cone:

Radius: 4cm

Height: 2cm

Plug in numbers for the variables and solve:

`SA=\pi (4)(4+√(2^2+4^2))`

`SA=106.46cm^2`
