Question

MEDAL AND FAN!!!!!! PLZ HELP ASAP!!!!!
how many times larger is the new volume of a cylinder if only the height tripled, and the radius remained the same?

3 times larger
6 times larger
9times larger
the volume stays the same.

Thnx n advance

btw.. pls tell me how u gt it..

Answer 1

@igreen, @iambatman

Answer 2

do you have an image of the cylinder @b.trail.coco4231?

Answer 3

no,i have SOS. I am homeschooled. tht is the actual question. @AMYCARTER

Answer 4

The equation for the volume of a cylinder is:
\[V_0= \pi r^2h\]
If you triple the height, you get:
\[V_{new}=\pi r^2 (3h)\]
Which is the same as saying:
\[V_{new}=3(\pi r^2 h)\]\[V_{new}=3V_0\]
So you can see that your new volume after tripling the height is just 3 times the starting volume, V(o). Doesn't matter what the actual volume is because we just want to know how the volume changed.
