My guys got me right? I’m giving brainliest

Answer:
1. 12
2. [tex]\pi[/tex] or about 3.14
3. 4.5[tex]\pi[/tex] or about 14.13
4. 12 + 5.5[tex]\pi[/tex] or about 29.27
Step-by-step explanation:
1. The rectangle is 6 by 2
6 * 2 = 12
2. They would combine to form a circle with radius 1, so [tex]\pi * 1^2[/tex] = [tex]\pi[/tex], or if you use 3.14 for pi you get 3.14
3. The radius is 3 and it's half of a full circle, so
[tex]\pi * 3^2 / 2= 4.5\pi[/tex], or if you use 3.14 for pi you get 14.13
4. Adding all of these together, you get 12 + 5.5[tex]\pi[/tex] or if you use 3.14 for pi you get 29.27
