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 length of of the radius of a circle?

You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).


How do you calculate the diameter of a circle?

If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius


How do you find the radius if you do not know the diameter?

You can measure it. Otherwise, you certainly have to know SOMETHING about the circle to calculate the radius, usually the diameter, the circumference, or the area. If you don't know anything at all about a circle, you can't find out the radius, either.


What may be calculated from its diameter?

If by "it" you mean a circle, once you know the diameter, you can calculate its radius, its circumference, and its area.


What is the mathematical formula for finding the radius of a circle?

To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius


How do you find the diameter of a circle when you know the radius?

Diameter = 2*Radius


How do you calculate radius when the have no radius and no diameter?

You use the information that you do have, and a formula that relates it to theradius or diameter of the circle. As an example: The circumference is very helpfulif you know it.


What is the radius for a circle?

To know what a radius is you have to kno what a diameter is. The diameter is the distance accross a circle through its center. The radius is half the diameter.


How to calculate area in a circle?

Depends on what you know. Like if you know the radius, square it and multiply it by pi. If you know the diameter, do the same thing as you do with the radius except do it after finding half of that diameter.


How dou find diameter?

You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it.

How do you calculate radius of the circle?

Based on what? - The radius is 1/2 the diameter. If it is the circumference you know, divide it by (2 x pi).


How do you figure out diameter?

Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
