Ask nicely. Rephrase how you asked
Since we are less busy. Take

square both sides
A^2=(PI*r)^2 (h^2-r^2)

divide both sides by PI^2

(A/PI)^2 -r^2h^2 +r^4=0 define a new variable, u=r^2

u^2-uh^2+(A/PI)^2=0 now use the quadratic formula

u=(h^2+-sqrt(h^4-4A^2/PI^2)/2

but u=r^2, so for r, take the square root of u above.
Note there are two solutions, life is not so simple in these equations

I need you to write it out and snap then upload the pictures here I will really appreciate

NDSMELODY:
here is my solution

here is my solution

Hhenryy:


You tried but you cannot cancel pi in the final solution. That is not mathematically correct.. You can either multiply through with 2pi or proceed to LCM, which will not simplify things either. So you can leave it at the penultimate step. It is correct to that level.

Cherez:
Well done Melody

my answer

dejt4u:
you're very wrong.. That your difference of 2 squares is wrong

dejt4u:
wrong.. Let's see your workings please

LamaNewton:

here it is sir
i've seen my error

NDSMELODY:
..........if i am wrong, you are wrong too because if u take square root of each portion at right hand side as u av done we have gotten thesame expression then.

dejt4u:
lol.. He got it wrong even before that last stage
