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

How do you find the radius of a circle only knowing the circumference?

The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.


What is the circumference when the radius is r?

To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr


What is the formula for finding the radius of a circle when you have the circumference?

Divide the circumference by 2*pi because 2*pi*radius = circumference


What is the Circumference of a circle with 20 radius?

The equation for finding the circumference of a circle is C=2πr.C= Circumference.π= Pi (3.14).r= Radius.Therefore, C=2π(20), so C=125.66.
