The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.

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

What is the new volume of a cylinder if the height and radius are doubled?

If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.


If the height and radius of a cylinder are doubled how will the volume of the cylinder be affected?

volume is related as radius squared x height soif both radius and height doubled volume increases 2 x 2 x 2 = 8 times


What happens to the radius if the volume of a cylinder is doubled?

It depends on whether the height remains unchanged or increases in the same proportion as the radius.


How does the volume of a cylinder change if the height is doubled?

The volume will be doubled.


How many times greater is the volume of a cylinder with a radius of 5 than a radius of 2.5?

Volume of a cylinder is given by the formula: V = πr2hIt is important to keep in mind that:If r is doubled then volume becomes four times....(1)Volume of the cylinder with radius of 2.5 units is equal to π(2.5)2h and volume of the cylinder with radius of 5 units is equal to 4π(2.5)2h. (By using the fact (1))So, it is clear that volume of the cylinder with greater radius is 4 times the volume of the cylinder with smaller radius.


What is the effect on the volume of a cylinder when the height is doubled?

its volume is also doubled...


What happens to the volume of a cylinder if the height is doubled and the diameter of the base is not changed?

since the volume of a right cylinder is height x area of base, the area of the baseis Pi * r^2 (r is radius which is 1/2 of diameter), so the area of the base did notchange, while the height is doubled so the volume is doubled.


What is the volume of a cylinder with a radius of 3.5 and the volume of 5?

If the volume of the cylinder is 5, then its volume is 5 and its radius doesn't matter.
