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

Recall that two angles are complementary if the sum of their measures is 90 degrees°. find the measures of two complementary ang
Julli [10]
Let x represent the smaller angle. Then the larger one is 20+4x. Since they are complementary, their sum is 90. (All measures are degrees.)

90 = x + (20+4x)
90 = 5x +20
70 = 5x
14 = x

The smaller angle is 14°.
The larger angle is 76°.
