To solve this problem, we are going to use the formula for finding the volume of a sphere, which is 4/3 * π * r³.
We can observe from the diagram that the diameter is 14 and we know that the radius is 1/2 of the diameter.
1/2 * 14 = 7
Thus, the radius of the sphere is 7.
Now, let's find the area by using the formula.
4/3 * π * r³ = 4/3π * 7³ = 4/3π * 343 = 457 1/3 * π ≈ 1436.76 feet³
Therefore, your answer is 1436.76 feet³, or the second option.
Hope this helps!
Answer:
$330,4
Step-by-step explanation:
$472-30/100*$472 = $330,4
option A is correct answer friend
Richard and Teo are 7 and 24.
7 times two is 14
24 is ten more than 14
31-7 is 24
Answer:
<h2>y = 2x + 5</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
=======================================
We have the points (-2, 1) and (-4, -3). Substitute:
![m=\dfrac{-3-1}{-4-(-2)}=\dfrac{-4}{-2}=2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B-3-1%7D%7B-4-%28-2%29%7D%3D%5Cdfrac%7B-4%7D%7B-2%7D%3D2)
![y=2x+b](https://tex.z-dn.net/?f=y%3D2x%2Bb)
Put the coordinates of the point (-2, 1) to the equation:
![1=2(-2)+b](https://tex.z-dn.net/?f=1%3D2%28-2%29%2Bb)
<em>add 4 to both sides</em>
![5=b\to b=5](https://tex.z-dn.net/?f=5%3Db%5Cto%20b%3D5)
Finally:
![y=2x+5](https://tex.z-dn.net/?f=y%3D2x%2B5)
