Answer:
D)The equation is f(x)=3x^2−9x+3, and the parabola opens upward.
Answer:
6.25π cm²
Step-by-step explanation:
pi = π
Circumference = 5πcm
Now first we should find radius(r)
2πr = 5π cm
pie will be cancelled and we get here
r = 5/ 2 cm
Therefore r = 2.5 cm
Now
Area (A) = πr²
= π * 2.5²
= 6.25π cm²
There is more than one solution. For example we could take:

and

Then:
