2 answers:
Answer:
72/25
cm² or 9.047786842... cm²
Step-by-step explanation:
Area of whole circle is 
×2.4² = 144/25
cm² or 18.09557368... cm²
Since it is a semi-circle, divide this value by 2 (or multiply by 0.5, either way, your halving it):
144/25
÷ 2 = 72/25
cm² or 9.047786842... cm²
Answer:
Step-by-step explanation:
area of semi circle=πr^2/2
=3.14*(2.4)^2/2
=3.14*5.76/2
=18.0864/2
=9.0432 cm^2
