Answer:

904.32 cubic ft

Step-by-step explanation:

To find the volume of a sphere, the formula is 4\pi\frac{r^3}{3}

First, 3.14 * 4 for 12.56.

The radius is 6, and that cubed is 216.

After that, divide 216 by 3 for 72

Then, 12.56 times 72, which gets you the final answer of  904.32 cubic ft.

(10 * 72) + (2 * 72) + (0.5 * 72) + (0.06 * 72)

720 + 144 = 864

864 + 36 = 900

900 + 4.32 = 904.32

What is the answer to this question smart people
Paladinen [302]
Answer:
SAS

Explanation:
To prove congruency by:
1- SSS:
Each side in the first triangle should be congruent to the corresponding side in the second triangle.
2- SAS:
Two sides and the INCLUDED angle between them in one triangle should be congruent to the corresponding two sides and the INCLUDED  angled in the second. If the angle is not included between the two sided, SAS becomes invalid
3- AAS:
Two angles and one side in one triangle should be congruent to the corresponding two angles and side in the other triangle

In the given triangles we have:
AS = KS
angle 6 = angle 9
SC is a common side between the two triangles

We can note that:
angle 6 is the angle included between AS and SC in the first triangle
angle 9 is the angle included between KS and SC in the second triangle

Therefore:
We have two sides and an included angle in the first triangle congruent to the corresponding two sides and the included angle in the second.

Therefore, we can prove the two triangles to be congruent using SAS postulate

Hope this helps :)

What expression can be used to find the height of the cone below?
poizon [28]

Answer: The height of the cone is

h = \frac{45}{4}

Step-by-step explanation:

<u>Step 1:-</u>

using formula Volume of the cone given base  and height of the cone is  V=\frac{1}{3}  (base)(height)

Given Volume of the cone is V = 30 ft^3

Given base of the cone is B = 8 ft^2

<u>Step 2</u>:-

V=\frac{1}{3}  (base)(height)

substituting values, we get

30 = \frac{1}{3} ( 8) ( h)

cross multiplication, we get

\frac{30 X 3 }{8}

simplification we get

h = \frac{45}{4}

<u>Final answer</u> :- The height of the cone is

h = \frac{45}{4}
