Answer:
1. 73.12, 2. 94.25, 3. 96, 4. 54, 5. 62.28, 6. 90.48
this is kinda rushed so you might want to check my answers
Explanation:
1. find the area of the rectangle and semi circle seperately then add
4*12 = 48, (8/2)^2 *pi /2 = 8pi = 25.12
48+25.12 = 73.12
2. find the area of the triangle and semicircle then add
11*10/2 = 55, (10/2)^2 * pi / 2 = 39.25
55+39.25 = 94.25
3. split the shape into a trangle and a square
12*(2+6+2)/2 = 60, 6*6 = 36
36+60 = 96
4. split into 2 rectangles
10*3 = 30, 6*4 = 24
30+24=54
5. find area of rectangle and subtract area of semicircle
4*14 = 56, (4/2)^2 * pi /2 = 6.28
56+6.28 = 62.28
6. area of circle minus area of rectangle
(16/2)^2 * pi /2 = 100.48, 2*5 = 10,
100.48-10= 90.48
