Webb21 apr. 2015 · The solid angle ( ω) subtended by any rectangle of size l × b at any point lying on the perpendicular axis at a distance d from the center is given by Standard formula [1] ω = 4 sin − 1 ( l b ( l 2 + 4 d 2) ( b 2 + 4 d 2)) Hence, by substituting l = 20 c m, b = 10 c m & d = 30 c m we can easily get the solid angle subtended by rectangle In astronomy, the sizes of celestial objects are often given in terms of their angular diameter as seen from Earth, rather than their actual sizes. Since these angular diameters are typically small, it is common to present them in arcseconds (″). An arcsecond is 1/3600th of one degree (1°) and a radian is 180/π degrees. So one radian equals 3,600 × 180/ arcseconds, which is about …
