Question

Find the perimeter of the window to the nearest hundredth.



perimeter: about
ft

Answer 1

`p = (1)/(2) * 2 * \pi * radius \\`

`p = 3.14 * (3)/(2) \\`

`p = 3.14 * 1.5`

`p = 4.71 \: \: ft`

Answer 2

`7.71ft`

Explanation:

Formula for finding circumference

`(1)/(2) \pi *d+d`

Diameter =
`3ft`

Substitue into equation:

`(1)/(2)\pi *3+3`

Solve:

`3.14*3=9.42\\(1)/(2) of9.42=4.71\\4.71+3=7.71`
