Answer: 1 / 2 x2 / 1 1 / 3 = 0.3333333333
Step-by-step explanation:
Divide: 11 / 2 = 5.5
Multiple: the result of step No. 1 * 2 = 5.5 * 2 = 11
Divide: the result of step No. 2 / 11 = 11 / 11 = 1
Divide: the result of step No. 3 / 3 = 1 / 3 = 0.33333333
We have two options in the case of the equation for parabola y=ax²:
1) in the case that a is negative the parabola opens down
2) in the case that a is positive the parabola opens up
So the correct answer is: if a is positive, the parabola opens up.
The circumference of a circle is 2PiR or PiD (Pi being 3.14) ( 2 x Radius x 3.14).
We have the diameter, 6. The radius is 0.5d or d/2.
Our radius is 3.
3.14 x 2 = 6.28
6.28 x 3 = 18.84
Your circle's circumference is 18.84 mm^2.
I hope this helps! :)
