What is the volume of a sphere with a radius of 1 foot? (use 3.14 for pi)

V≈4.19ft³

Step-by-step explanation:

The volume of a sphere with a radius of 1 foot is 4.19ft³.

In order to find this:

V=4

3πr3=4

3·π·13≈4.18879ft³

54.864 meters

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
