ok so remember
area=pir^2
area=256pi

256pi=pir^2
divide both sides by pi
256=r^2
squaer root
16=r

find r and d
d=2r
d=2(16)
d=32

radius=16ft
diameter=32ft

RADIUS:A=3.14*r^2
area=256pi

256*3.14=3.14*r^2
divide both sides by 3.14
256=r^2
square root
16=r


DIAMETER:
3.Now double the radius to get the diameter.32 is the diameter.


radius=16ft
diameter=32ft
