Answer:
134 cubic centimeters
Step-by-step explanation:
The extended part is basically the volume of HALF A SPHERE.
First, the volume of full sphere is:
![V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
Hence, the half sphere volume would be:
![Half \ Sphere = \frac{\frac{4}{3}\pi r^3}{2}=\frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=Half%20%5C%20Sphere%20%3D%20%5Cfrac%7B%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%7D%7B2%7D%3D%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
We know the diameter is 8, radius is HALF OF THAT, so
Radius = 8/2 = 4
Substituting, we find (remembering to use 3.14 as pi):
![\frac{2}{3}\pi r^3\\=\frac{2}{3}\pi (4)^3\\=\frac{2}{3}(3.14)(64)\\=133.97](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3%5C%5C%3D%5Cfrac%7B2%7D%7B3%7D%5Cpi%20%284%29%5E3%5C%5C%3D%5Cfrac%7B2%7D%7B3%7D%283.14%29%2864%29%5C%5C%3D133.97)
To the nearest cubic centimeter, the answer is:
134 cubic centimeters
Answer:
The answer is 19.
Step-by-step explanation:
3x+1+12=9x+1
3x+13=9x+1
13=6x+1
12=6x
x=2
3(2)+1+12=19
Answer:
7.5?
Step-by-step explanation:
Answer:
30 dogs
Step-by-step explanation:
100% = 50
1% = 50 ÷ 100 = 0.5
60% = 0.5 x 60 = 30
Answer:
Yes.
Step-by-step explanation:
It satisfies our definition of a function. For every x, there is one and only one value of y.
