2*(pi)*r/4 + 100 + 100

2*3.14*100/4 + 100 + 100

50*3.14 + 100 + 100
A little over 150 +200 = a little over 350

Option C

This question is asking you to find the perimeter of the circle.

Since this is a quarter of a circle we need to divide the perimeter by 4 and add the remaining two sides ( reason -- by perimeter formula you will only find the length of the curved part)

so the answer is 2*Pi*r / 4 +100+100 [ where r = radius = 100]

this will give you (3.14*100/2)+200 = 357
