Answer:
ans is (D)500/3 π unit^3
Explanation :
Formula for volume of sphere is 4/3 π r^3 .
You have one of the answers correct. The fraction 4/8 is equal to 1/2
Other answers are: 5/10, 10/20, and 6/12
If you reduced each of those fractions, you'd get to 1/2.
You can use a calculator to find that
4/8 = 0.5
1/2 = 0.5
5/10 = 0.5
10/20 = 0.5
6/12 = 0.5
All fractions mentioned lead to the same decimal value, so this confirms all of the fractions are equivalent to one another.
10x10x10x10, you have to multiply 10 by 10 four times, since it's 10 to the power of 4.
