Answer:
-4
Step-by-step explanation:
Derivate the function
solve the equation y'= 0
The extrme value of y is reached in -5
y = 3(-5+5)²-4= -4
Circumference of circle = π × Diameter
= π × 18 cm
= 56.54867 or 56.54 to 1 dp
the correct answer is A
need to solve for Y using X =0 and plot all the points
