Question

Pls help round to the nearest tenth, if needed.

Answer 1

Answer:

$\pi$ or 3.1

Step-by-step explanation:

The total area of the circle is $3^2\pi$. The central angle of the shaded region is 40 degrees so we have to multiply $3^2\pi$ by $\frac{40}{360}$ or $\frac{1}{9}$. 3 squared is 9 so 9$\pi$ times $\frac{1}{9}$ is just equal to $\pi$. $\pi$=3.14159265... rounded to the nearest tenth is 3.1
