Answer: 111.72 m^2 if they want round its 112
Is from O to C 14m
A=pixr^2
3.14x14^2= 615.44 m/2 half circle = 307.72
Area of triangle A= 1/2bh. .5x28x14=196
307.72-98=196= 111.72 m^2
Step-by-step explanation:
%error=100(estimated-actual)/actual
%error=100(96-(96-16))/(96-16)
%error=100(16/80)
%error=1600/80
%error=20%
She overestimated how many bracelets she would sell by 20%
