The area (a=pir^2) of a circle with a radius of r is given by the formula and its diameter is given by (d = 2r) arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.

A=pi (d/2) ^2

d^2=2A/pi

d=sqrt2A/pi

A=4pid^2

d=sqrt4A/pi

d^2=4A/pi

A=pid^2/4

4A=pid^2

Riya Blankenship · Answer 1

A = pi r^2

d = 2r

r = d/2

A = pi (d/2) ^2

A = pi d^2/4

4A = pi d^2

d^2 = 4A/pi

d = sqrt (4A/pi)

d = 2 sqrt (A/pi)
