When you want to find where a function is increasing or decreasing, you want to look at the sign of the derivative. Here, the derivative is ...
f'(x) = 4x^3 -100x = 4x(x^2 -25) = 4x(x +5)(x -5)
This has zeros at x=-5, x=0, and x=5. The sign of the derivative will be positive when 0 or 2 factors have negative signs. The signs change at the zeros. So, the intervals of f' having a positive sign are (-5, 0) and (5, ∞).
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21

Answer:
531 cm^2 approx
Step-by-step explanation:
Given data
Diameter= 26 cm
radius= d/2= 26/2= 13 cm
Area= πr^2
substitute
A= 3.142*13^2
A= 3.142*169
A= 530.998
A= 531 cm^2 approx
