i think the answer would be 12 cm. because Volume= Height x Area.
We need to find the area. How do we do that? Simple:
Area, is the same as the area of a circle.
Area of circle= pi x r^2
We already have the radius.
BUT, we must be careful how we use it. It's still in centimeters.
Convert it to meter, and the area becomes:
Area= 3.1415926547 x (0.05^2)
Now, we have the volume and the area.
But before you do that, you must note a very very important detail. To be able to convert from Liter to Meter, you need to know that, 1 liter= 1 dm^3
1 liter= 0.001 meter^3.
Anyways, when you perform all calculations, you should get Height=12 cm.
So the answer is B.
Thank you but could you explain that in a way a 7th grader who is crap at math, could understand it....?
Sorry for any inconvenience--
