Given:
Diameter of ball = 8 cm
To find:
The volume of the ball.
Solution:
We know that the radius of sphere is half of is diameter.
It is given that the the diameter of ball is 8 cm. So, the radius of the ball is:
![r=\dfrac{8}{2}](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7B8%7D%7B2%7D)
![r=4](https://tex.z-dn.net/?f=r%3D4)
The radius of the ball is 4 cm.
The volume of a sphere is:
![V=\dfrac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
Where r is the radius of the sphere.
Putting
in the above formula, we get
![V=\dfrac{4}{3}(3.14)(4)^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%283.14%29%284%29%5E3)
![V=\dfrac{4}{3}(3.14)(64)](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%283.14%29%2864%29)
![V=267.946667](https://tex.z-dn.net/?f=V%3D267.946667)
![V\approx 267.95](https://tex.z-dn.net/?f=V%5Capprox%20267.95)
Therefore, the volume of the ball is about 267.95.
So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. <span>And how much will she pay?
Solution:</span> <span><span>
1. </span>19 for each t-shirt</span> <span><span>
2. </span>Total of $38 if not provided with 30% off</span>
<span><span>3. </span>19 x 0.3 = 5.7</span>
<span><span>4. </span>Hence 30% of $19 is $5.7</span>
<span><span>5. </span>Next is we deduct $5.7 which is 30% of $19.</span> <span><span>
6. </span>19 – 5.7 = $13.3</span> <span><span>
7. </span>Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.</span> <span><span>
8. </span>19 + 13.3 = 32.3</span>
<span><span>9. </span>Conclusively, she will pay $32.3 for the shirts.</span>

Answer:
The probability that Justin will practice soccer this evening is 16%.
Step-by-step explanation:
The probability that John will practice soccer is given by the product of the probability that it won't snow and the probability that he'll practice soccer. This is shown below:
practice soccer = (1 - 0.6)*0.4
practice soccer = 0.4*0.4
practice soccer = 0.16
The probability that Justin will practice soccer this evening is 16%,
