Answer: 226.2 or 226.19 depending on how they want you to round
Step-by-step explanation:
Take the diameter and turn into radius; 12
Formula for circle area is A = pir^2
A = pi12^2
452.39 is the total circle area
452.39/2
226.195 is half of the circle area, or the semicircle's area
hundredth should be 226.20 but they might want 226.19
