Diameter of a circle = 28 m
Then, radius of the circle will be :
Thus, the radius of this circle = 14 m
Area of circle :
Thus, the area of this circle = 615.44 m²
Circumference of circle :
The circumference of this circle = 87.92 m
Therefore, the area of this circle = 615.44m² and the circumference of this circle = 87.92m
Answer:
120 inches of strands
Step-by-step explanation:
finding the diagonal
=
= 26 inches
perimeter of the window = 2(10+24)
= 68 inches
total strands needed to be purchased = [(2×26)+68] inches
= 120 inches of strands
Answer:
zero
Step-by-step explanation:
Answer:
CDA and BDA are the same
Step-by-step explanation:
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
