Given:
The diameter of a sphere is 19 cm.
To find:
The volume of the sphere.
Solution:
We have,
![Diameter=19\text{ cm}](https://tex.z-dn.net/?f=Diameter%3D19%5Ctext%7B%20cm%7D)
![Radius=\dfrac{19}{2}\text{ cm}](https://tex.z-dn.net/?f=Radius%3D%5Cdfrac%7B19%7D%7B2%7D%5Ctext%7B%20cm%7D)
The volume of the sphere is
![V=\dfrac{4}{3}\pi r^2](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20r%5E2)
where, r is radius.
Putting
in the above formula.
![V=\dfrac{4}{3}\times \dfrac{22}{7}\times (\dfrac{19}{2})^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%20%28%5Cdfrac%7B19%7D%7B2%7D%29%5E3)
![V=\dfrac{4}{3}\times \dfrac{22}{7}\times \dfrac{19}{2}\times \dfrac{19}{2}\times \dfrac{19}{2}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%20%5Cdfrac%7B19%7D%7B2%7D%5Ctimes%20%5Cdfrac%7B19%7D%7B2%7D%5Ctimes%20%5Cdfrac%7B19%7D%7B2%7D)
![V=\dfrac{75449}{21}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B75449%7D%7B21%7D)
![V=3592.80952](https://tex.z-dn.net/?f=V%3D3592.80952)
![V\approx 3592.8](https://tex.z-dn.net/?f=V%5Capprox%203592.8)
Therefore, the volume of the sphere is 3592.8 sq. cm.
Answer:
x · -4
Step-by-step explanation:
-2×-4=8
8×-4=-32
-32×-4=128
Solving for x
6x^2 + 23x - 4 = 0
Factoring
(6x - 1)(x + 4) = 0
6x - 1 = 0 or x+ 4 = 0
X = 1/6 or x = -4

Answer:
$8.45
Step-by-step explanation:
if he has $26 to start and spends 17.55 on his friends, he has 8.45 leftover to spend on himself, but since he bought his friends pancakes for 17.55 their pancakes would have cost 8.775 each which suggests that Jeremiah likely cannot afford his own pancakes
