Answer: 13.722 km ; or, write as: 13 13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ;
___________________________________________________
or, write as: A = L * w ;
________________________
Given: A = 247 km² ;
L = 18 km ;
w = "y" ;
________________________
Find: "y"
______________________________
A = L * w ;
______________________________
Plug in our values:
______________________________
247 km² = 18 km * "y" ; solve for "y" (in units of "km") ;
_____________________________
18 y = 247 ;
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
18 y / 18 = 247 / 18 ;
_____________________________________________
to get:
_____________________________________________
y = 13.7222222222222222...... km ; round to: 13.722 km
or; y = 13 13/18 km .

Let
be the length of the square, then the area is
. Hence, the side is the positive root of the area, which is
Answer:
The answer to your question is Volume = 36000π cm³ in terms of π
Volume = 113040 cm³
Step-by-step explanation:
Data
Volume of a ball = 4/3 πr³
radius = 30 cm
π = 3.14
Process
1.- Substitute the values given in the formula
Volume = 4/3 π(30)³
2.- Simplification
Volume = 4/3π(2700)
Volume = 36000π cm³ in terms of π or
Volume = 36000(3.14) = 113040 cm³
