let the radius of the circle = r units
area of the circle = 2* circumference
pi*r^2 = 2*2*pi*r
r^2/r =4*pi/pi
r=4
diameter = 2r
d=2*4
d=8units
area of the circle = 2* circumference
pi*r^2 = 2*2*pi*r
r^2/r =4*pi/pi
r=4
diameter = 2r
d=2*4
d=8units

according to question
2pi r=pi r^2/2
4pi r=pi r^2
4r=r^2
4=r
hence, diameter of circle is 8 unit
2pi r=pi r^2/2
4pi r=pi r^2
4r=r^2
4=r
hence, diameter of circle is 8 unit
