Area = ∫_0 ^1 (4−y^2 ) dy   = 4y − (y^3 /3) ∣_0 ^1 = ((11)/3)
Area=01(4y2)dy=4yy3301=113

correct is 3+(2/3)=((11)/3)
correctis3+23=113

from y=0 to y=1.  not your method is wrong, but your  calculation is wrong. the result is  not (8/3), but ((11)/3).  ∫(4−y^2 )dy=4y−(y^3 /3)≠4y−((4y^3 )/3)    but we can also get the result without  integral, the area is 3+(2/3)=((11)/3).
fromy=0toy=1.notyourmethodiswrong,butyourcalculationiswrong.theresultisnot83,but113.(4y2)dy=4yy334y4y33butwecanalsogettheresultwithoutintegral,theareais3+23=113.

but sir. i think this question not   complet. my understand the question  must be the area bounded the   curve y = (√(4−x)) , y=0 , y=1 , x = 0
butsir.ithinkthisquestionnotcomplet.myunderstandthequestionmustbetheareaboundedthecurvey=4x,y=0,y=1,x=0
