Geometry Round volume to nearest tenth

Mathematics
1 answer:
-Dominant- [34]2 years ago
4 0

Answer:

volume= 912.9ft^{3} (not sure how you want to round the answer. it could be rounded to 913 or left as 912.9)

Step-by-step explanation:

<u>volume of cone:</u> to find the height of the cone, subtract the cylinder height from the total height (H-h= cone height)

<u></u>V=\pi r^2\frac{h}{3} \\V=\pi (5.6)^2(\frac{6.8}{3} )\\V=\pi (31.36)(2.2666...)\\V=71.08057\pi \\V=223.3062

<u>volume of cylinder:</u>

<u></u>V=\pi r^2h\\V=\pi (5.6)^2(7)\\V=\pi (31.36)(7)\\V=219.52\pi \\V=689.6424

<u>add them together:</u>

<u></u>V=223.3062+689.6424\\V=912.9486

The two triangles (ABC and ADE) can be shown to be similar (which I'll do below). Their corresponding parts are also similar. 
Step One
Prove Similarity.
A is common to both triangles              Construction
<ABC = <ADE                                       Given as right angles.

By the AA Theorem both triangles are similar.

Step Two
Find x

AD is to AB as DE is to x
AD = 3 + 4 = 7
AB = 3
DE = 6
7 / 3 = 6/x Cross multiply
7x = 3 * 6
7x = 18 Divide by 7
x = 18/7
x = 2.571 <<<<< answer
