To calculate the average density of the hollow sphere learn the radius and density.
What is radius?
Simply halving the circle's diameter yields the radius formula. The radius of the ring is the line segment formed when we join a point on a circle's circumference to the exact center. The radius of a circle is the distance separating its center from its perimeter.
What is density?
When a material is packed tightly, it is said to have a high density. Its definition is the ratio of mass to volume. Density begins with the letter D. density formula is given as = m/V for objects with masses m and volumes V.
Volume of solid sphere = 4 pi r^3 / 3
= 4 x pi x 5^3 / 3
= 523.6 cm^3
mass = 350 g
average density = mass / volume
= 0.668 g/cm^3 Or 668 kg / m^3
If Sphere is hollow, then also it will acquire same volume in the space.
hence average velocity will not change.
Therefore, its average density is 0.668 g/cm^3 Or 668 kg / m^3
