A homeowner is building a circular fire pit in his backyard. He plans to outline the pit with bricks and cover the space inside
saw5 [17]

Answer:

<em>1) the exact distance = 9.428571429 feet</em>

<em>the approximate distance = 9.4 feet</em>

<em></em>

<em>2) the exact area = 7.071428571 ft^2</em>

<em>the approximate area = 7 ft^2</em>

<em></em>

Step-by-step explanation:

Required diameter d = 3 feet

1) The distance around the outside of the pit is the circumference of the circle that will be formed by this circular fire pit.

circumference of a circle is given as = πd = \frac{22}{7} x 3 = 9.428571429 feet

the exact distance = 9.428571429 feet

the approximate distance = 9.4 feet

2) The area of the circle that will be formed = \pi d^{2}/4 = \frac{22 *3^{2} }{7*4} = 7.071428571 ft^2

the exact area = 7.071428571 ft^2

the approximate area = 7 ft^2

Which graph represents x - 1 ≤ 3
MAVERICK [17]
The first graph. 

The  equation is x - 1 \leq 3
In order to solve it, you need to get x by itself.
Add 1 to both sides.  3+1=4
x \leq 4

Since this is your sign \leq the arrow has to point towards the left, and the circle needs to be colored in.
