Answer:

Step-by-step explanation:
From the question we are told that
Width of circular path 
Inner Diameter 
Outer diameter
(inner diameter + 2 circular path width)

Generally the equation for inner circumference of the circle
is mathematically given by



Generally the equation for outer circumference of the circle
is mathematically given by



Generally the difference in length of the two circumference
is mathematically given by



Answer:
y=18.2 x=5.6
Step-by-step explanation:
sin 73 = y/19
19 sin 73 = y
cos 73 = x/19
19 cos 73 = x
The point-slope form:

We have the points
and
.
Substitute:

The standard form: Ax + By = C

Answer:
7.07
Step-by-step explanation:
<h2><u>Length</u></h2>
a square has equal length on each side
hence is the perimeter is 20 it means that :
each side is 20/4 = 5
we can make a diagonal line which create 3 right angled triangles
2 sides of the triangle are 5 , this is the base and the height
to find the length we can make use of the Pythagoras theorem
c^2 = a^2 + b^2
c is the hypotenuse ( the diagonal;)
a and b are the opposite and adjacent
hence :
c^2 = 5 ^2 + 5^2
c^2 = 50
c = 
c = 7.071
to 3sf
<h3><u>diagonal length = 7.07</u></h3>
