Answer: C) Cannot be done
Taking the square root of a negative number is not possible unless you involve complex numbers. If your teacher has not introduced that topic yet, then you just simply say "cannot be done" or something along those lines.
 
        
             
        
        
        
18) (10)7d/10=35(10)
7d/7=350/7
d=50
21) 3/4 w=27
(4/3)3/4 w=27(4/3)
w=36

Answer:
             3V
r = ∛ ( ---------- )
             4π
Step-by-step explanation:
Please, enclose the fraction 4/3 inside parentheses, to eliminate any possibility of misreading this fraction.  Also note that this formula MUST include "pi," symbolized by π.
V = (4/3) π r³  This formula does NOT include "m," which is a unit of measurement, not a variable.
Our task is to solve this formula for the radius, r.
Divide both sides by (4/3) π, to isolate r³.  This results in:
       v               (4/3) π r³
-------------   =  -----------------
   (4/3) π             (4/3) π
                       
                        V              3V
Then r³ = --------------  =  --------
                    (4/3) π           4π
and r is found by taking the cube root of the above result:
             3V
r = ∛ ( ---------- )
             4π
