I have a problem. I have to find the Volume of a group beans. Now I measured the bean's diameter, but I wasn't able to get Volume in the lab. Is there a way to get it? The equation to find volume is V = (pi)r^2h... (pi times r squared, times H). Volume of a solid is cm^3. There are two variables missing, V and h. Now the diameter I have is 15.5cm... so the radius is 7.75cm. So I have V = 3.14 * 7.75^2 * h Is it possible to find the other two varibles?
