Applying the expression for the circumference of circle, we found the diameter as 16.86 yards
<h3>Mensuration of Flat shape</h3>
Given Data
Let us apply the expression for the circumference of a circle
Circumference = 2πr----------1
But r = d/2
hence put r = d/2 in the expression above
Circumference = 2πd/2----------2
Circumference = πd
Substitute our given data
53 = 3.142*d
Make d the subject of formula we have
d = 53/3.142
d = 16.86 yards

60 inches.
Because you will do 5x12= 60
You get 12 from the inches in a foot!
Hope this help!!
The equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4
<h3>Direct and indirect variation</h3>
An indirect variation is also known as the inverse variation
If the variable y is indirectly proportional to x , this is expressed as:
y = k/x
where
k is the variation constant
If the variation constant is -4, then;
y = -4/x
Hence the equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4
