Consider a right cone with radius 2 and height 6. its volume is v = π(2)26, or 8π units3.

if the height is changed to 3, does this have the same effect on the volume as changing the radius to 1?

if the height is now 3, then the new volume is π units3.

if the radius is now 1, then the new volume is π units3.

therefore, changing the height to half of its original value and changing the radius to half of its original value does the volume. halving the height of the cone the volume, while halving the radius of the cone results in the volume.

4, 2, not have the same effect on, halves, 1/4

Step-by-step explanation:

The correct answers are:

A. 4

A. 2

A. Not have the same effect on.

C. Halves

B. 1/4

If the height is now 3, then the new volume is 4 units. If the radius is now 1, then the new volume is 2 units. Therefore, changing the height to half of its original value and changing the radius to half of its original value does not have the same effect on the volume. Halving the height of the cone halves the volume, while halving the radius of the cone results in 1/4 the volume.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
