Answer:
<h2>d = 52 in</h2><h2>C = 6π mm²</h2>Step-by-step explanation:
The formula of a circumference:
r - radius
d - diameter
We have .
Calculate the diameter using :
<em>divide both sides by π</em>
-------------------------------------------------------------------------
If a circle inscribed in a square, then the diameter of a circle and a side of a square are congruent (have the same length).
We have the area of the square:
The formula of an area of a square:
s - side
Substitute:
The formula of a circumference
d - diameter
d = s → d = 6 mm
Substitute:
