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

As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.


Does the area of a circle double if its diameter doubles?

The area is four times as large if the diameter doubles.The area of a circle is A = (pi)r2 or (pi)(diameter/2)2Since d is squared, it increases the area by the square of 2 if the diameter is doubled.Try calculating the area for a diameter of 2m, 4m and 8m to prove this.

How many square feet in a twenty four inch diameter circle?

The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'

What number is in the circle to find radius and diameter?

There are four common measurements of a circle, radius, diameter, circumference, and area. Here is how they are related. Diameter is how far across it is at the widest point. Radius is 1/2 of diameter. Diameter X pi = circumference. pi = 3.1416 Area = pir2


What happens to the area of a circle when the diameter is halved?

It is reduced by a quarter. If you halve the you also halve the diameter The area (A) of a circle is = pi x (radius)squared. If you halve the radius and then square it then to balance the equation the area must be divided by Four.

How long is a 4 foot circle?

Normally a four foot circle is four feet in diameter, unless you're talking about four foot in circumference. As a circle is perfectly round. Therefore, it is either 4 ft or 8 feet long, depending on whether you are measuring the radius or the diameter to determine your 4 ft circle. Good luck Terry PS it’s also 4 or 8 feet wide…. I just kill me.
