Answer:
100%
Step-by-step explanation:
When the dimensions double, the perimeter doubles.
The percent change can be found from ...
percent change = ((new value)/(old value) -1) × 100%
Filling in your values, you have ...
percent change = ((2×(old perimeter))/(old perimeter) -1) × 100%
= (2 - 1) × 100%
= 100%
The perimeter increases by 100% from the first garden to the second.
Answer:

, 
, 
, base, h, height, same, , , 3

The volume of a cone is equal to the volume of a cylinder that has the same base and height. The formula for the volume of a cone is 
. stands for the area of the base and h is the height of the cone. Knowing this, we could quickly find the volume of a cone that has the same base and height as a cylinder with a volume of 9 cubic cm. Since the volume of a cone is the volume of a cylinder (with the same base and height), we would multiply 9* to obtain a volume of 3 cubic cm.
