Answer: The formula to calculate the radius of a sphere if we know the volume is: Cubic root [3V/(4∏)].
Solution:
The formula for the volume (V) of a sphere is:
V=(4∏/3) r^3
Solving for r: Multiplying both sides of the equation by 3/(4∏):
3/(4∏) V = 3/(4∏) [(4∏/3) r^3]
3V/(4∏) = r^3
Cubic root both sides of the equation (raising to the power 1/3):
Cubic root [3V/(4∏)] =Cubic root (r^3)
Cubic root [3V/(4∏)] = r
r = Cubic root [3V/(4∏)]
Answer: The answer would be B. 
Because we know that she bought 6 bags of 36 jewels. So the first part we would need to solve would be the total number of jewel she purchased. Which would be 
. Then, you must find the total number of jewels that she used. Which would be 
. This means that the equaltion would be the total number of jewels-the total numnber of jewels used. Aka: 
Hello There!
It is Arithmetic.
Hope This Helps You!
Good Luck :)
X= 2 the answer would be 2 because 4x2 = 8 and 8+8= 16
