What is the approximate area of a sector with radius equal to 8 and measure of arc equal to 300 degrees?

The area of the full circle is (pi) R2 = 64 pi.

We call a full circle "360 degrees".

The 300-degree sector is (300/360) = 5/6 of the full circle, so its area is

(5/6) x (64 pi) = 167.55 square units (rounded)
