Where " T " is the rotation period in seconds, " r " is the equatorial radius, and ? is the latitude.
12.
Its outer edge is located at a radius of about (; = equatorial radius of Jupiter or ) and coincides with the orbit of Jupiter's smallest inner satellite, Adrastea.
13.
The difference between the semi-major axis ( equatorial radius ) of the Hayford ellipsoid and that of the modern WGS84 ellipsoid is; for Helmert's ellipsoid it is only.
14.
Where " T " is the rotation period in seconds, and r _ { \ rm eq } is the equatorial radius ( usually also the maximum radius used above ).
15.
Dr . Fischer disagreed with the established figure for the oblateness of the earth ( the fraction by which the polar axis is foreshortened by the equatorial radius ), which had remained unchallenged since 1924.
16.
The equatorial radius of the star was estimated to be 2.03 solar radii, and the polar radius 1.63 solar radii a 25 % increase of the stellar radius from pole to equator.
17.
Thus " r " 3 = 8.5243?0 12 km 3, whose cube root is 20, 427 km; subtracting the equatorial radius of Mars ( 3396.2 km ), we have 17, 031 km.
18.
Thus, " r " 3 = 8.5243?0 12 km 3, the cube root of which is 20, 427 km; subtracting the equatorial radius of Mars ( 3396.2 km ) gives 17, 031 km.
19.
:If we look at the sidereal period and equatorial radius of each planet from Earth to Neptune, it looks like the sidereal period is approximately equal to one day multiplied by the inverse of the cube root of radius ( in Earths ):
20.
The WGS 84 spatial reference system describes Earth as an oblate spheroid along north-south axis with an equatorial radius of a = 6378.137 km and an inverse flattening of 1 / f = 298.257 \, 223 \, 563.
