  2. Volume of an n-ball - Wikipedia

    en.wikipedia.org/wiki/Volume_of_an_n-ball

    The volume of a n-ball is the Lebesgue measure of this ball, which generalizes to any dimension the usual volume of a ball in 3-dimensional space. The volume of a n -ball of radius R is R n V n , {\displaystyle R^{n}V_{n},} where V n {\displaystyle V_{n}} is the volume of the unit n -ball , the n -ball of radius 1 .

  3. Ball (association football) - Wikipedia

    en.wikipedia.org/wiki/Ball_(association_football)

    Regulation size and weight for a football is a circumference of 68–70 cm (27–28 in) and a weight of 410–450 g (14–16 oz). The ball is inflated to a pressure of 0.6–1.1 bars (8.7–16.0 psi) at sea level. [20] This is known as "Size 5". Smaller balls, Sizes 1, 3, and 4, are also produced for younger players or as training tools. [20]

  4. Bowling ball - Wikipedia

    en.wikipedia.org/wiki/Bowling_ball

    The USBC and World Bowling promulgate bowling ball specifications. USBC specifications include physical requirements for weight (≤16 pounds (7.3 kg)), diameter (8.500 inches (21.59 cm)—8.595 inches (21.83 cm)), surface hardness, surface roughness, hole drilling limitations (example: a single balance hole including the thumb hole for "two-handed" bowlers [3]), balance, plug limitations, and ...

  5. Tenpin bowling - Wikipedia

    en.wikipedia.org/wiki/Tenpin_bowling

    Neighboring pins are centered 12 inches (30 cm) apart, leaving a space of 7.234 inches (18 cm) between pins that can be bridged by a bowling ball of regulation diameter (8.5 inches (22 cm)). [ 4 ] Pin carry essentially determines the probability of achieving a strike assuming the ball impacts in or near the pocket—and varies with several ...

  6. Unit of volume - Wikipedia

    en.wikipedia.org/wiki/Unit_of_volume

    6 volumetric measures from the mens ponderia in Pompeii, a municipal institution for the control of weights and measures (79 A. D.). A unit of volume is a unit of measurement for measuring volume or capacity, the extent of an object or space in three dimensions.

  7. Volume element - Wikipedia

    en.wikipedia.org/wiki/Volume_element

    Consider the linear subspace of the n-dimensional Euclidean space R n that is spanned by a collection of linearly independent vectors , …,. To find the volume element of the subspace, it is useful to know the fact from linear algebra that the volume of the parallelepiped spanned by the is the square root of the determinant of the Gramian matrix of the : (), = ….
