The circumference (in terms of "π") is: " 12π in. " .
__________________________________________________________
The circumference (using "3.14" as an approximation for "π") is: " 37.7 in. " .
__________________________________________________________
Circumference, "C" = π* d ; (d = diameter = 12 in.);
C = π* d = π * 12 in. = " 12π in. " (in terms of "π").
Or, using the approximation, "π ≈ 3.14" ;
C = 3.14 * (12 in.) = 37.68 inches ; round to: " 37.7 in. " .

Answer:
First row: 5(1)-4; 1; (1,1)
Second row: 5(2)-4; 6; (2,6)
Third row: 5(3)-4; 11; (3,11)
Step-by-step explanation:
Plug in the value of x to get the value for u then write the coordinates. So first value of x is 1 so put a 1 where the x is in this equation 5x -4. 5(1) - 4 =1 so the value of y is 1. So when x is 1 y is equal to 1 (1,1). Do the same for 2 and 3.
Answer:
64 degrees
Step-by-step explanation:
since x is corresponding to 64, they are congruent.
Answer:
Step-by-step explanation:
To prove a quadrilateral a parallelogram we prove,
1). Length of opposite sides are equal.
2). Slopes of the opposite sides are same.
Length of AB = 
= 
= 
Length of BC = 
= 
Length of CD = 
= 
Length of AD = 
= 
Therefore, AB = CD and BC = AD (Opposite sides are equal in length)
Slope of AB = 
= 
= -1
Slope of BC = 
= -3
Slope of CD = 
= -1
Slope of AD = 
= -3
Slope of AB = slope of CD and slope of BC = slope AD
Therefore, AB║CD and BC║AD
Hence ABCD is a parallelogram
