Answer:
The scientific notation is the way which scientists effortlessly handle very large numbers as well as very small numbers. In order to convert into scientific notation, move the decimal place in the number till you get the coefficient between 1 and 10. The 3,920,000,000,000 in scientific notation is 3.92 x 10^12.

Answer:
1³ + 2³ + 3³ = 36
Step-by-step explanation:
Sum of 1³, 2³, 3³
Sum = addition (+)
1³
= 1 × 1 × 1
= 1
2³
= 2 × 2 × 2
= 8
3³
= 3 × 3 × 3
= 27
1³ + 2³ + 3³
= 1 + 8 + 27
= 36
1³ + 2³ + 3³ = 36

Answer: 4in
Step-by-step explanation:
Volume of a cylinder = πR²H
Volume of a cone = 1/3πr²h
πR²H = 1/3πr²h
π is very common so it could be cancelled, so the equation now becomes
R²H = 1/3r²h
3R²H = r²h
Now substitute for the values
h = 3 x 2² x 3
--------------
3²
= 9 x 4/9
= 4in.
Therefore, the height of the cone
h = 4in.
