Check the picture below.
so, the diameter of the sphere, is the same as a side's length of the cube, bearing in mind that all sides in a cube are the same length.
since all sides in the cube are "d", then its volume is V = d*d*d or V = d³.

since the diameter is twice as much as the radius, thus d = 2r, or namely d = 18.
therefore, the volume of the cube will be V = 18³.

Answer:
144
Step-by-step explanation:
exponents first:
then division: 100/5 = 20
now we have: 20 x 4 + 64
then multiply: 20 x 4 = 80
then add: 80 + 64 = 144
Answer:
Option C is correct.
Step-by-step explanation:
We have been given total 8 data
Data is : 12,15,18,20,23,23,28
Here, n=7
Median is
Median is 20.
When one data is added n=8
The median of even number of data is
Median is
Median is
4th terms is 20
5th terms is 23
Since, median should not be change hence,
Median will be 20.
Therefore, option C is correct.
