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 4 Likes 1 Share |

NDSMELODY:Well done Melody |
Re: Please Someone Help Me Solve This Difficult Math by Hhenryy: 10:40am On May 03, 2020 |
NDSMELODY: 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. |

Hhenryy:thank u bro. |
Re: Please Someone Help Me Solve This Difficult Math by NDSMELODY(m): 11:00am On May 03, 2020 |
Cherez:thanks |
Re: Please Someone Help Me Solve This Difficult Math by dejt4u(m): 12:40pm On May 03, 2020 |
NDSMELODY:you're very wrong.. That your difference of 2 squares is wrong |
Re: Please Someone Help Me Solve This Difficult Math by dejt4u(m): 12:41pm On May 03, 2020 |
Hhenryy:lol.. He got it wrong even before that last stage |

Re: Please Someone Help Me Solve This Difficult Math by dejt4u(m): 12:44pm On May 03, 2020 |
LamaNewton:wrong.. Let's see your workings please |
Re: Please Someone Help Me Solve This Difficult Math by NDSMELODY(m): 12:51pm On May 03, 2020 |
dejt4u:in what way sir.......if possible post your solution |
Re: Please Someone Help Me Solve This Difficult Math by LamaNewton(m): 12:58pm On May 03, 2020 |
dejt4u:here it is sir i've seen my error

Re: Please Someone Help Me Solve This Difficult Math by Nobody: 1:07pm On May 03, 2020 |
You can simplify further and rationalize to get the answer above me.

Re: Please Someone Help Me Solve This Difficult Math by NDSMELODY(m): 1:09pm On May 03, 2020 |
LamaNewton:..........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. |
Re: Please Someone Help Me Solve This Difficult Math by Homeboiy: 1:31pm On May 03, 2020 |
next time bring statistical questions and I will help . |
Re: Please Someone Help Me Solve This Difficult Math by LamaNewton(m): 2:03pm On May 03, 2020 |
NDSMELODY:no,it wouldn't ours are way different |
Re: Please Someone Help Me Solve This Difficult Math by Hhenryy: 2:19pm On May 03, 2020 |
dejt4u: oops! didn't even pay close attention to the difference of two squares stage. he got the interpolation wrong there. cc: NDSMELODY |
