Best ResponseYou've already chosen the best response.0if you're integrating in 'dy' .. your limits will be functions of x

Best ResponseYou've already chosen the best response.0anyway... plug in the limits on 'x' ... ( 0 ... srt(9y^2) ) and then evaluate with respect to dy

Best ResponseYou've already chosen the best response.0yes but then we need to plug in 3 into \[\sqrt{93^{2}}\] wich equals 0 in the rad
