Answer:

75.36 feet of edging material

Step-by-step explanation:

The formula to calculate the length of a circumference is:

C = 2 * pi * r

Where C is the length and r is the radius.

If the circular patio has a radius of 12 feet, we can use the formula to calculate the length of the circular patio:

C = 2 * 3.14 * 12 = 75.36 feet

It will be needed 75.36 feet of edging material.

iragen [17]

Answer:

provides a procedure to hand-draw a square and a circle of equal area

Step-by-step explanation:

According to Vitruvian Man, an arm span and height have a nearly perfect correspondence in the human body. As a result, the body is placed perfectly inside a square. Buildings and other works of man should also occur depending on these proportions. All of this ties in with the problem of finding a procedure to hand-draw a square and a circle of equal area.

What is the sum of 3 consecutive odd integers is -39
trapecia [35]
Answer: The three consecutive odd integers are:  -15, -13, and -11 .
_______________________________________________________
Explanation:
_____________________________________________
  x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
 in which "x" is one of the integers, 
           "(x + 2)" is the next consecutive odd integer;
           "(x + 4)"  is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
     x + (x + 2) + (x + 4) = -39  ;
_________________________________________________________
          1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________  
                   3x + 6 = -39 ;
______________________________________________
               Subtract  "6" from EACH side of the equation:
______________________________________________
                    3x + 6 − 6  =  -39 <span>− 6 ;
____________________________________________________
        to get:   3x = -45 ;
____________________________________________________
           Divide EACH side of the equation by "3" ;
____________________________________________________
                 3x / 3 = -45 / 3 ;
_____________________________________________________
        to get:   x = -15 ;
______________________________________________________
     x + 2 =  -15 + 2 = -13 ;
_______________________________________________________
     x + 4 =  -15 + 4 =  -11 .
___________________________________________________
Are: -15, -13, and -11 ;  Consecutive odd integers?  YES!
___________________________________________________
Does:  -15 + (-13) + (-11)  =? = -39 ??
_____________________________________________________
           -15 </span>− 13 <span>− 11 = ? 39 ??  YES!
____________________________________________________
Answer: The three consecutive odd integers are:  -15, -13, and -11.
