. If the radius is doubled and the height is halved what is the ratio of the new volume to the original volume

photoshop1234 [79]

Answer: Ratio of new volume to original volume is 2:1.

Step-by-step explanation:

Let the radius of cylinder be 'r'

Let the height of cylinder be 'h'

Original volume of cylinder will be

$V=\pi r^2h$

If radius get doubled,

New radius be '2r'

If height get halved,

New height be will be

$\frac{h}{2}$

so, Volume of cylinder becomes

$Volume=\pi (2r)^2\times \frac{h}{2}=\pi \times 4r^2\times \frac{h}{2}\\\\Volume=2\pi r^2h$

Ratio of new volume to the original volume is given by

$2\pi r^2h:\pi r^2h\\\\2:1$

Hence, Ratio of new volume to original volume is 2:1.

What does the constant term in the polynomial 4x2 + 9 represent?

shusha [124]

Answer:

The constant in the polynomial is 9. A constant number is a number that does not change during the equation. This equation is 4x² + 9. Since you are just adding 9 the number of 9 does not change. If you were multiplying 9 it would not be a constant anymore because it does not stay the same throughout the equation.

Hope This Helps :)
