Answer:
1,256 dm^2 and 400π dm^2
Step-by-step explanation:
The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2

It is negative only when the number itself is negative.
hence, sometimes.
-151/120x -1 or 1\120 × (-151x -120)
Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7
