V = 343 π cm³

Step-by-step explanation:

Given:

Diameter = 14 cm

Radius = 7 cm

Height = 7 cm

Solution:

Volume of Cylinder =

V = (3.14)(7)²(7)

V = (3.14)(49)(7)

V = 343 π cm³

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
