Question

If we triple the radio is of a cylinder what will be effect on its volume

Answer 1

Answer:

If the height of a cylinder is considered as 'h' &

radius as 'r'

then it's volume is = π(r^2)h

So, when the radius is tripled, the volume will be 3 squared = 9 times than the previous one.

Hope, this helps.

Answer 2

Answer:

Change = Volume of new cylinder/volume of old cylinder

change = πR²h/πr²h

change = π(3r)²h/πr²h

change = 9/1 = 9

volume will increase 9 times
