2. degree of a polynomial is the highest of the degrees of its monomials (individual terms) with non-zero coefficients
3. a coefficient is a number used to multiply a variable.
4. A exponent refers to the number of times a number is multiplied by itself

Answer:
57.0 cm
Step-by-step explanation:
We know that the radius of the filament is 1 mm. Taken to cm, is 0.1 cm.
From the density and mass, we can get the volumen of the bangle:
d = m/V ----> V = m/d
Solving for V:
V = 25 / 14 = 1.79 cm^3
We can assume that a bangle is a cylinder so:
V = π*r^2*h
1.79 = 3.14 * 0.1^2 * h
h = 1.79 / 3.14 * 0.01
h = 57.0 cm
There all wrong though ? how could the others be like that but the answer choices way off
