hmm? what do you mean?
OpenStudy (jdoe0001):
I think you're meant to get the perimeter first, then round it up
OpenStudy (is3535):
so so b
OpenStudy (jdoe0001):
well.... what's did you get without rounding though?
OpenStudy (is3535):
The figure consists of 3 sides of a square which are 4 + 4 + 4 = 12 cm
The "perimeter" of the semicircle is
2 * PI * r / 2 =
PI * r =
3.14159265 * 2 =
6.2831853072
Adding this to the 12 cm equals
18.2831853072 =
18.28 rounded so the answer is b
