Answer 1

Answer:

The area is 18$\pi$ squared. The perimeter is 24$\pi$.

Step-by-step explanation:

Area: 6 squared is 36. Divide by two to get 18.

Perimeter: The diameter of each semi-circle is 6. 6 times $\pi$ is 6$\pi$. Divide by two, so the perimeter of each semi-circle is 3$\pi$. Add that to the diameter of the big semi-circle, which is 6$\pi$. 12$\pi$ + 12$\pi$(two semi-circles) to get 24$\pi$.
