Step-by-step explanation:
Given : Ariel's garden is planted in the shape of a square and has an area of 81 square feet. If she plans to put a fence around the perimeter of the garden.
To find : How much fencing will she need?
Solution :
The area of the garden square is 81 square feet.
The formula of area of square is
The side of the square is 9 feet.
The fence around the perimeter of the garden is
So, The fence around the perimeter of the garden is 36 feet.
Therefore, Option 3 is correct.

Answer:
= (-2,5)
Step-by-step explanation:
To Find:
Solution :
Referring the given graph
We can find the coordinates of and
Coordinates of = (-7,1)
Coordinates of = (5,4)
Thus Coordinates of = (-7+5,1+4) = (-2,5)
Thus = (-2,5)
So, the point = (-2,5) is shown on the attached graph file
Given that, a sphere has a surface area of about 999 square millimeters.
Formula to find the surface area of sphere is,
S= 4πr² Where r = radius of the sphere and S= surface area.
Given S= 999 square millimeters.
So, we can write:
4πr² = 999
4 * 3.14 * r² = 999 Since, π = 3.14
12.56 *r² = 999
Divide each sides by 12.56.
r² = 79.53821656
r = √79.53821656 Taking square root to each sides of equation.
r = 8.918420071
So, r = 8.918 Rounded to nearest thousandth.
So, radius of the sphere is 8.918 millimeters.
