X^3 - x^2 - 2x = 0
x ( x^2 - x - 2 ) = 0
x (x-2) (x+1) = 0
x = 0
x-2 = 0 --> x = 2
x+1 = 0 --> x = -1
x = 0, x = 2, x = -1
Answer:
B
Step-by-step explanation:
So we have the formula:
And we want to solve it for r.
So, let's first divide both sides by π and h. This will cancel out the right side:
Now, take the square root of both sides:
And we're done!
Our answer is B.
I hope this helps!
Also known as the hypotenuse leg theorem. It states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.' This is kind of like the SAS, or side-angle-side postulate. Congruent triangles.
