Question

Work out the perimeter of this semicircle take pie to be 3.142 radius in image attached thanks (:

Answer 1

56.562 cm

Solution,

Radius(R)= 11 cm

Perimeter of semi-circle:

`\pi \: r + 2r`

`= 3.142 * 11 + 2 * 11`

`= 34.562 + 22`

`56.562 \: cm`

Hope this helps...

Good luck on your assignment..

Answer 2

`\boxed{P = 56.55751919 cm}`

Explanation:

Perimeter of semicircle =
`(2\pi r)/(2) + 2r`

Where r = 11 cm

=> P =
`(2(3.142)(11))/(2) + 2(11)`

=> P =
`34.55 + 22`

=> P = 56.55751919 cm
