# [Answer] The volume of air inside a rubber ball with radius r can be found using the function V(r) = 4/3πr³. What does V(5/7) represent?

###### Answer: the volume of the rubber ball when the radius equals 5/7 feet
The volume of air inside a rubber ball with radius r can be found using the function V(r) = 4/3πr³. What does V(5/7) represent?

In three dimensions the volume inside a sphere (that is the volume of a ball but classically referred to as the volume of a sphere) is = = ≈ ⋅ where r is the radius and d is the diameter of the sphere. Archimedes first derived this formula by showing that the volume inside a sphere is twice the volume between the sphere and the circumscribed cylinder of that sphere (having …

A cricket ball is a hard solid ball used to play cricket.A cricket ball consists of a cork core wound with string then a leather cover stitched on and manufacture is regulated by cricket law at first-class level. The trajectory of a cricket ball when bowled through movement in the air and off the ground is influenced by the action of the bowler and the condition of the ball and the pitch …

Hard spheres are widely used as model particles in the statistical mechanical theory of fluids and solids. They are defined simply as impenetrable spheres that cannot overlap in space. They mimic the extremely strong (“infinitely elastic bouncing”) repulsion that atoms and spherical molecules experience at very close distances.

In geometry the convex hull or convex envelope or convex closure of a shape is the smallest convex set that contains it. The convex hull may be defined either as the intersection of all convex sets containing a given subset of a Euclidean space or equivalently as the set of all convex combinatio…
