The formula for the area of a circle is πr^2. Plug in the given radius for r. You now have π*2.2^2. Square the 2.2 first. 2.2^2 is 4.84. Now take that answer of 4.84 and multiply it by π or 3.14 as indicated in the directions for the problem. 4.84 * 3.14 = 15.1976
Now round that answer to the nearest tenth as the directions said to. 

Your answer should be:
15.2 ft.^2

Step-by-step explanation:

First we must find the missing number, for that we apply a simple rule of three:

3. 4

27 ------ x

x = 27 (4) / 3 = 36

Now we just do the sum:

27 + 36 = 63

A group of neighbors are constructing a community garden that is 80 m wide and 40 m long the top to vertex are plotted below at
Ainat [17]

Question Correction

A group of neighbors are constructing a community garden that is 80 meters wide and 40 meters long. The top two vertices are plotted below at (10, 70) and (90, 70). What are the coordinates for the bottom two vertices of the garden?

Answer:

(10,30) and (90,30)

Step-by-step explanation:

The community garden is 80 m wide and 40 m long.

The top two vertex are plotted at: (10, 70) and (90, 70).

Horizontal Distance =90-10=80

This serves as the Width of the garden.

Since the length is 40m, the bottom two vertex can be derived by the transformation: (x,y-40).

(x,y-40)-->(10, 70)=(10,30); and

(x,y-40)-->(90, 70)=(90,30)

The coordinates for the two bottom vertices are (10,30) and (90,30).
