Question

What is the surface area of this cone? Use a ~ 3.14 and round your answer to the nearest hundredth. 7 yd 6 yd square yards

Answer 1

Given:-

`h=7,r=6`

To find the surface area.

So now we use the formula,

`A=\pi r(r+\sqrt[]{h^2+r^2})`

So now we substitute so we get,

`\begin{gathered} A=\pi6(6+\sqrt[]{7^2+6^2}) \\ A=\pi6(6+\sqrt[]{49+36}) \\ A=\pi6(6+\sqrt[]{85}) \\ A=6\pi(6+\sqrt[]{85}) \end{gathered}`

So the required solution is,

`A=6\pi(6+\sqrt[]{85})`
