Circumference = 2 * radius * pi (where pi is approx = 3.14159)
So Radius = Circumference / (2 * pi)

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
