First, find the volumes of each figure.
Remember that the volume of a sphere =
![\frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3)
Smaller sphere:
![\frac{4}{3}\pi*10^3](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%2A10%5E3%20)
4188.79 Cubic inches.
Larger sphere:
![\frac{4}{3}\pi*20^3](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%2A20%5E3)
33510.32 Cubic inches.
33510.32 - 4188.79 = 29321.53 cubic inches
Hope that helps!
Answer:
The first is 3 and the second is 18
Step-by-step explanation:
Let the first number be x and the second number be 6x
The sum of the two is 21 which means
x+6x= 21
7x=21
Divide both sides by 7
X=3
And the second number is six times the first which means
6(3)=18
Therefore,the first number is 3 and the second number is 18
P=1
work: 2x10=20
30-20=10
10/10=1
1x10=10
10+20=30
