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

4^7 (4 x 4 x 4 x 4 x 4 x 4 x 4 = 16384) is not the same as 7^4 (7 x 7 x 7 x 7 = 2401)
