A regulation baseball has mass 145 g and diameter 22.86 cm. Will this ball float
or sink in water?
1. Get the volume of the sphere (baseball). You re given the diameter, and you can get the radius by dividing this by 2. You are also given the formula:
V,sphere = 4/3 * π * r^3
Just substitute the value of radius to get V.
2. Divide the given mass by volume to get density of sphere:
d = m/V
3. Compare the density of sphere to density of water (which is 1 g/cm^3). If density of sphere is greater than density of water, it will sink. Otherwise, it'll float.
hope this helps :3
