Answer:
The radius of the volleyball is 8.3 inches
Step-by-step explanation:
Given
![r = \sqrt{\frac{3v}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7B3v%7D%7B4%5Cpi%7D%7D)
![v = 288](https://tex.z-dn.net/?f=v%20%3D%20288)
Required
Determine the value of r
To do this, we simply substitute 288 for v and 3.14 for π in the given equation.
This gives
![r = \sqrt{\frac{3v}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7B3v%7D%7B4%5Cpi%7D%7D)
![r = \sqrt{\frac{3 * 288}{4 * 3.14}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7B3%20%2A%20288%7D%7B4%20%2A%203.14%7D%7D)
![r = \sqrt{\frac{864}{12.56}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7B864%7D%7B12.56%7D%7D)
![r = \sqrt{68.7898089172}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B68.7898089172%7D)
![r = 8.29396219651](https://tex.z-dn.net/?f=r%20%3D%208.29396219651)
(Approximated)
Hence;
<em>The radius of the volleyball is 8.3 inches</em>
Step-by-step explanation:
![3x + \frac{2}{4} x + 1 = 5x + \frac{1}{3} x + 2 \\ 1.833 x+ 1 = 0 \\ 1.833x = - 1 \\ x = 0.545](https://tex.z-dn.net/?f=3x%20%2B%20%20%5Cfrac%7B2%7D%7B4%7D%20x%20%2B%201%20%3D%205x%20%2B%20%20%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%202%20%5C%5C%201.833%20x%2B%20%201%20%3D%200%20%5C%5C%201.833x%20%3D%20%20-%201%20%5C%5C%20x%20%3D%200.545)
The first one is a triangle because: The two smaller sides of a triangle must add up to be larger than the longest side.
14 + 12 = 26 > 19
