    Answer:

    C.

    Step-by-step explanation:

    Radius = 16 ÷ 2 = 8

    \frac{45}{360} *8^2*\pi =25.1 (3sf)

    You can first find the total area of the circle which is 64\pi.

    Then, you can find the area of the slice of the pizza, if you take the ratio of the angle it creates with the total angle of a circle (360.)

    For example, a semicircle’s are would be  \frac{180}{360} *8*\pi.
