Answer:
12 units
Explanation:
This problem can be solved if we take into account the equation for a sphere

where we took that the radius is 13 units. If we take z=5 and we replace this value in the equation of the sphere we have

where we have taken x2 +y2 because if the equation of a circunference.
In this case the intersection is made when we take z=5, for this value the sphere and the plane coincides in values.
Hence, the radius is 12 units

Answer: 4.9 g/cm^3
Explanation.
!) Data
mass = 49 g
Volume = 10 cm^3
2) Formula
Density = mass / volume
Density = 49 g / 10cm^3 = 4.9 g/cm^3
This is a problem where you only need to know the formula and subtitute the numbers to calculate.
The formula of density is the very same definition: mass per unit of volume.
So, as you had the mass and the volume you just need to plug the values in the formula density = mass / volume.
