Answer:

Step-by-step explanation:
- Height of cone (h) = 7 cm
- Formula for Volume of cone is given as:
- Plugging the values of h and r in the above formula, we find:
 
        
             
        
        
        
144=(x+7)^2  take the square root of both sides...
12=x+7  subtract 7 from both sides...
x=5
So the original was a 5m square.

255=WL and you are told that W=L+2 so the equation becomes:
255=(L+2)L
255=L^2+2L
L^2+2L-255=0
L^2+17L-15L-255=0
L(L+17)-15(L+17)=0
(L-15)(L+17)=0  Since L>0...
L=15yd, and since W=L+2, W=17yd so
length=15, width=17yd
