Answer:
1767.1 inches cubed
Step-by-step explanation:
The volume of a ball, or a sphere, is: 
, where r is the radius.
Here, the radius is r = 7.5. So, plug in this value: 
562.5 pi is about 1767.1 inches cubed.
Thus, the volume is 1767.1 inches cubed.
Hope this helps!
A ratio of 2:3 is the same as 2/3 now we can divide out 2/3 to .6666666 and then multiply by 10 to get 6.666666 or you could just multiply 10 x 2/3 to get 20/3 and then divide to get 6.66666.
Answer:
Tbh, I think the easiest way is to count on your fingers. I still do it, however I can now do my chart tables to 17x17 by using fingers. People may tease, however, it is a good way to make sure you do not mess up as much as memorizing. You should memorize, and count on your fingers at the same time to solve extremely fast.
Step-by-step explanation:
9x4
You can pretend that your thumb equals nine, and count 9 plus 9 plus 9 plus 9, with each other finger, such as your ring finger, pointer, middle, and pinky , which equals 36. 5x9, you have five fingers on each hand, so each finger can equal nine (I don't care if people say that your thumb isn't a finger, just take it and move on lol).
The answer is A because if you do 10*10*10 that would give you 1k and if u multiply that by 2 you get 2k
