choices:
A.129 square inches
B.113 square inches
C.110 square inches
D.44 square inches

Answer 1

area of a circle is \[\pi r ^{2}\] and for a square it is L*W

7*13 = 91

the radius is 7/2 or 3.5 but since you only have half a circle the area formula would just be divided by 2 \[\frac{ \pi r ^{2} }{ 2 }\] upon substituting 3.5 for r you get 19.24

adding hat to 91 you get 110.24 or 110
