Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
the discriminant is:
D = (-1)^2 - 4*(-2)*6 = 49
We have a positive discriminant, which means that we have two real solutions.

How to find the discriminant?</h3>
For the general quadratic equation, the discriminant is:
a*x^2 + b*x + c = 0
The discriminant is:
D = b^2 - 4ac
In this case, the quadratic equation is:
6*x^2 - x - 2 = 0
Then we have:
a = 6, b = -1, c = -2
Replacing that in the discriminant equation:
D = (-1)^2 - 4*(-2)*6 = 49
We have a positive discriminant, which means that we have two real solutions.
