Answer:
100
Step-by-step explanation:
The original area is (200 m)×(300 m) = 60000 m². You want an area that is ...
(200 +x)×(300 +x) = 120000
60000 +500x +x² = 120000 . . . . eliminate parentheses
x² +500x -60000 = 0 . . . . . . . . . . subtract 120000
(x +600)(x -100) = 0 . . . . . . . . . . . . factor
The positive value of x that makes a factor zero is x = 100.
The value of x is 100.

Answer:
About 50.14 Centimeters
Step-by-step explanation:
The formula for the volume of a cylinder is:
Now, let's plug in the values. (We'll use 3.14 for pi.)
All we do now, is solve for r. Divide 76 on both sides...
Divide 3.14 on both sides...
Lastly, find the square root on both sides.
Therefore, the r, or the radius, is around 50.14 centimeters. Hope this helps!
