Question

if a radius of a cylinder is r and height is h how will the vol. change if the height is doubled
​

Answer 1

Answer:

HERE IS YOUR ANSWER MATE

Step-by-step explanation:

If the radius of a cylinder is doubled and height is halved, the volume will be doubled. If the radius of a cylinder is doubled and height is halved, the volume will be doubled.

Answer 2

$\bold{AnsweR:}$

• Doubled volume will be become π*r^2*2h,that is volume will also be doubled

• Then the volume becomes π*r^2/2*2h=πr^2 h. Volume remains same.

• Then volume becomes, πr^2/2*h. that is ,volume becomes half .

Here r = r / 2, h = 2h  

∴ Volume of cylinder = π(r / 2)² 2h = 1 / 2 πr²h

Original volume of cylinder = πr²h  

Volume w.r.t. original volume of cylinder  

= (1 / 2) πr²h  /  πr²h = 1 / 2.
