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 diameter of a circle in the terms of pi?

To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi


How do you find area if you know the diameter?

radius = diameter/2 area of a circle in square units = pi*radius2


How do you find the radius and diameter of the circle if you know the area?

Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)


Beneficial to know the area of a shape?

well it is benificial to know the area of a shape because to find the circumference, radius, and diameter u must know the area of the shape well it is benificial to know the area of a shape because to find the circumference, radius, and diameter u must know the area of the shape


How do you find the area of a semi-circle if you know the diameter?

A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.


If you know the diameter of a sphere you can find its surface area?

Yes, that's true. The surface area is (the square of the diameter) multiplied by (pi).


How do you get the diameter of a circle?

That depends on what you know. If you know the radius of the circle, double it to get the diameter. If you know the circumference of the circle, divide it by π to get the diameter. If you know the area of the circle, find its square root and divide the result by π to get the radius then multiply by 2 to get the diameter.


How do you find the diamter of a circle if you know the area?

In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.


How do I figure the area of a circle by diameter?

To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)


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.


How do you find diameter of a circle with the area of 58.69?

Diameter is 8.64444


Why would it be beneficail to know the area of a shape?
