What is the volume of the cylinder with a diameter of 16ft and height of 10ft?

 r = 16/2 = 8

using 3.14 for π since you don't say what to use

2x3.14x8x10 = 502.4

2x3.14x8^2 = 401.92

401.92 + 502.4 = 904.32 cubic ft.

 Round answer as needed

4.

step-by-step explanation:

it have the same area.brainliest

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
