50
Step-by-step explanation:

__
We make use of the special form for the difference of squares:
(a+b)(a-b) = a²-b²
Since -2 is less than -1 (-2<-1) You will plug -2 into the first equation. -2+8=6
Your answer is 6.
Answer:
Area = 13.0900 ft²
Step-by-step explanation:
Area of sector = θ/360 × πr²
We are assuming it's the area of the minor sector that we are asked to find.
Therefore,
θ = 360 - 300 = 60°
r = 5 ft
Plug in the values
Area of minor sector = 60/360 × π × 5²
Area = 13.0899694
Area = 13.0900 ft² (to 4 decimal places)
