Answer:
f(-2) = 2 and f(0) = 0.
Step-by-step explanation:
The piece wise function is given by, f(x) = x³ for x ≠ - 2 and f(x) = |x| for x = - 2.
Now, as defined above at x = -2, f(x) = |- 2| = 2
So, f(-2) = 2
Again, at x = 0, f(x) = x³ = (0)³ = 0.
So, f(0) = 0.
Hence, f(-2) = 2 and f(0) = 0. (Answer)
Given:
Area of a circle, A=50.265 sq. units.
Radius of circle, r = 4 units.
To find:
The value of π to the nearest thousandth.
Solution:
Formula for area of a circle is



Now, using
expression, we can find the value of π.




Approximate the value to the nearest thousandth (three digits after decimal).

Therefore, the approximated value of π is 3.142.
