3) 56.5 square inches
4) 557.1 sq in
5) 216 sq in
Step-by-step explanation:

2) 80 - 78.54 = 1.46
3) 12/2 = 6

= 113.1
113.1/2 = 56.5
4) area of square: 20(20) = 400
area do semicircle:
/2 = 157.1
400 + 157.1 = 557.1

triangle: 144/2 = 72
144 + 72 = 216
It is in the tens place, so the digit's value is 70.
