The curved surface area of cylinder is 154 cm square the total surface area is three times its curved surface area find the volume of cylinder plzzz give the full answer and very fast its so urgent fo**So, as beforecurved surface area=154=2h(pi)rtotal surface area=3 times curvedtotal=3 times 154total =462total=curved+2(area of base)462=154+2(area of base)subtract 154308=2(area of base)divide 2154=area of basearea of base=pir^2solve for radius154=pir^2aprox pi to 3.14154=3.14r^2divide both sides by 3.1449=r^2square root both sides7=rRADIUS=7find hiehgtwe know that 154=2h(pi)rsubsittue 3.14 for pi and 7 for r 154=h2(3.14)(7)154=h43.96divide both sides by 43.963.5=hvolume=height times pi times r^2volume=3.5 times pi times 7^2volume=3.5 times pi times 49volume=171.5 times pivolume=171.5piaprox pi to 3.14volume=3.14(171.5)volume=538.51radius=7 cmheight=3.7 cmvolume=171.5pi cm^3 or 538.51 cm^3**...
