Question

If you find the answer to both of them can you give an explanation

Answer 1

5.
`150.8m^2`

6.
`301.6in^2`

Explanation:

5.

`A=2\pi rh+2\pi r^2=2*\pi *3*5+2*\pi *3^2\\=150.8m^2`

6.

`A=2\pi rh+2\pi r^2=2*\pi *6*2+2*\pi *6^2\\=301.59in^2`

rounded to nearest tenth

`301.6in^2`

Answer 2

5. SA= 150.8 6. SA=301.6

Explanation:

You need to use the formula A=2π*r*h+2π*r^2, and you need to plug in the height and radius, for number 6 since it gives the diameter you need to divide it by 2 to find the radius. Once you plug everything in just a calculator to solve the rest and then round to the nearest tenth.
