Answer:
816
Step-by-step explanation:
Just multiply, 3 by 16 by 17 so 3 x 16 x 17 is 816.
Answer:
<u>The length of GI is 90.06 units </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
GH = 60 units
HI = 42 units
∠H = 123°
2. Using the Law of Cosines, we can find the length of GI, this way:
GI² = GH² + HI² - 2 * GH * HI * cos ∠H
Replacing with the real values:
GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°
GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545
GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545
GI² = 3,600 + 1,764 + 2,746.8
GI² = 8,110.8
GI = √ 8,110.8 = 90.06 units
Answer:
74.958 lb-in
Step-by-step explanation:
We are given that
Natural length of spring=l=6 in
After stretching, the length of spring=8.3 in
Weight=W=9 lb
Extension in the sprig=8.3-6=2.3 in
By hook's law
Using the formula
Extension in the spring when the length of spring after stretching to 12.2 in=12.2-6=6.2 in
Work done, W=
![W=[\frac{3.9x^2}{2}]^{6.2}_{0}](https://tex.z-dn.net/?f=W%3D%5B%5Cfrac%7B3.9x%5E2%7D%7B2%7D%5D%5E%7B6.2%7D_%7B0%7D)
7.2 because you just add the -4.8 to cancel out the -4.8 on the right side. and you get 7.2
Answer:
169π or 530.93
Step-by-step explanation:
The formula for the area of a circle is πr²
Here, the radius is given to be 13.
So, let's just plug it into the formula as r
π x 13²
π x 169
169π
The radius is 169π. If you want to multiply out the π you would get 530.93, which is equivalent of course.
