Let x= height of the tree
By ratio and proportion:
6ft/4.5ft = x/15ft
4.5ft x = 6ft (15ft)
x= 20ft.

How long in feet would the shadow be for an object which is 18.6 feet tall?
In addition to the height of the object, the length of its shadow depends on a few other things that are not described in the question. -- Is the object standing straight upright ? -- Is the shadow cast on the ground or on sometheing else? -- If on the ground, is the ground level ? -- What is the altitude (angle) of the sun ?

How did human beings know that the earth was a sphere before the use of satellites?
Some very wise man noticed that the shadow cast from a stick placed vertically in the ground was a different angle at exactly noon than the angle of shadow cast at exactly noon from a vertically placed stick in the ground at a location further north. By employing mathematics, he was able to deduce that the earth is in fact, roundish.

Why are shadows cast on the ground?
A shadow is a place where direct light has been blocked from reaching in the presence of direct light around it. Because most direct light is received from the sun, the shadow is cast on the ground. The light would normally have reached the ground, but something (a person, a building, a cloud, etc.) blocked the light between the sun and the ground resulting in a shadow.
A 15ft light pole cast a 25ft shadow a 20 foot light pole castes a X shadow?
15 / 25 = 20 / x Cross multiply and solve. 15*x=25*20 15x=500 x = 500/15 = 33.33 ft. ■

Does the full moon cast a shadow on the ground like the sun does?
Yes, it certainly can cause a shadow. Of course, it needs an object between the Moon and ground to actually cast the shadow.During a solar eclipse the Moon itself casts a shadow, but that's at New Moon, not Full Moon.Often it's hard to see a moonlight shadow, because of all the artificial lighting in towns.

Why do birds not cast their shadows while flying high in the sky?
Birds flying up in the sky do not cast their shadow because the source of light (sun) is too large compared to the object (bird) and the umbra of the shadow formed on the screen (ground) is very small, negligible.So it is tough to see its shadow on the ground. (P.S. If this is a VNS student reading this for Physics research, then I'm pretty sure you're in my grade and you know who I am)
What makes shadows big and small?
Its all to do with the angle of the light source and how the shadow is cast on the surface. A low sun for example, will give a long shadow on the ground, while a shorter shadow occurs when the sun is more overhead.
