Question

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

Answer 1

Answer:

$\boxed{P = 56.55751919 cm}$

Step-by-step explanation:

Perimeter of semicircle = $\frac{2\pi r}{2} + 2r$

Where r = 11 cm

=> P = $\frac{2(3.142)(11)}{2} + 2(11)$

=> P = $34.55 + 22$

=> P = 56.55751919 cm

Answer 2

Answer:

56.562 cm

Solution,

Radius(R)= 11 cm

Perimeter of semi-circle:

$\pi \: r + 2r$

$= 3.142 \times 11 + 2 \times 11$

$= 34.562 + 22$

$56.562 \: cm$

Hope this helps...

Good luck on your assignment..
