Information: - A baseball is a ball used in the sport of the same name , baseball . The ball features a rubber or cork center , wrapped in yarn , and covered , in the words of the Official Baseball Rules '' with two strips of white horsehide or cowhide , tightly stitched together . '' It is 9.00 -- 9.25 inches ( 228.60 -- 234.95 mm ) in circumference , ( 2.86 -- 2.94 in or 72.64 -- 74.68 mm in diameter ) , and masses from 5.00 to 5.25 ounces ( 141.75 to 148.83 g ) . The yarn or string used to wrap the baseball can be up to one mile ( 1.6 km ) in length . Some are wrapped in a plastic - like covering . A significant characteristic of the baseball is the stitching that holds together the covering of the ball . After a ball has been pitched , these raised stitches act like wings on a plane , catching the wind and causing the ball to swerve slightly on its way to the catcher . Whether the ball swerves to the right , to the left , downward , or a combination thereof , and whether it swerves sharply or gradually , depends on which direction , and how fast , the stitches have been made to spin by the pitcher . See , for example , curveball , slider , two - seam fastball , four - seam fastball , sinker , cutter . - A sphere (from Greek "sphaira", "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball, (viz., analogous to a circular object in two dimensions). - A perimeter is a path that surrounds a two-dimensional shape. The word comes from the Greek "peri" (around) and "meter" (measure). The term may be used either for the path or its lengthit can be thought of as the length of the outline of a shape. The perimeter of a circle or ellipse is called its circumference. - In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. The word "diameter" is derived from Greek "" ("diametros"), "diameter of a circle", from "-" ("dia-"), "across, through" + "" ("metron"), "measure". It is often abbreviated DIA, dia, d, or . - The circumference (from Latin "circumferentia", meaning "carrying around") of a closed curve or circular object is the linear distance around its edge. The circumference of a circle is of special importance in geometry and trigonometry. Informally "circumference" may also refer to the edge itself rather than to the length of the edge. Circumference is a special case of perimeter: the perimeter is the length around any closed figure, but conventionally "perimeter" is typically used in reference to a polygon while "circumference" typically refers to a continuously differentiable curve.

Information: - The Nautilina is the last suborder of the Nautilida and the only nautiloids living since the end of the Triassic. The Nautilina, proposed by Shimanskiy, is basically the Nautilaceae of Kummel, 1964, defined by Furnish and Glenister, but differs in omitting two families, the Paracenoceratidae and Pseudonautilidae which instead are placed in the Liroceratina. - The Nautilaceae form one of five superfamilies that make up the Nautilida according to Bernard Kummel (1964), and the only one that survived past the Triassic. The Nautilaceae comprise six families: Nautilidae, Paracenoceratidae, Pseudonautilidae, Cymatoceratidae, Hercoglossidae, and Aturiidae. Shimanskiy (1957) separated the Paracenoceratidae and Pseudonautilidae from his near equivalent Nautilina and added them to the Lyroceratina, expanding the equivalent Clydonautilaceae and bringing it into the Jurassic. The Nautilaceae are represented by "Nautilus" and "Allonautilus", genera included in the Nautilidae. - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets. - Ammonoids are an extinct group of marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs are more closely related to living coleoids (i.e., octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living "Nautilus" species. The earliest ammonites appear during the Devonian, and the last species died out during the CretaceousPaleogene extinction event. - The nautilus (from the Latin form of the original Ancient Greek "", 'sailor') is a pelagic marine mollusc of the cephalopod family Nautilidae, the sole extant family of the superfamily Nautilaceae and of its smaller but near equal suborder, Nautilina. - Dimeroceratidae is one of three families in the Dimeroceratoidea, a goniatid superfamily included in the Ammonoidea; extinct shelled cephalopods with adorally convex septa and usually narrow ventro-marginal siphuncles. - Dimeroceratoidea , formerly Dimerocerataceae , is one of six superfamilies in the gonititid suborder Tornoceratina which lived During the Devonian . Five families are included , the Dimeroceratidae being the type family . Gonitites , to which they belong , are primitive ammonites sensu lato , extinct shelled cephalopods more closely related to living animals like squids and octopodes than to similarly shelled nautiloids such as the modern genus Nautilus . - A cephalopod (pronounced or ) is any member of the molluscan class Cephalopoda (Greek plural , "kephalopoda"; "head-feet"). These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishermen sometimes call them inkfish, referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.
