How to find the diameter of a circle with area 26 sq.units ?

find diameter of a circle with area

area = 26
r =  sqrt( A / PI )
radius = sqrt( 26 / PI )
radius = 2.8762
So the radius is 2.8762
d =  r * 2
diameter = 2.8762 * 2
diameter = 5.7524
So the diameter is 5.7524

Circle :

Circle is a perfect round shape.

Circle Formulas :

A =  PI * r * r

C =  2 * PI * r

d =  r * 2

r =  C / ( 2 * PI )


where,

d = diameter
A = area
C = circumference
r = radius
