1.	TSA of cyclinder is 462 cm and CSA is one third of TSA find the cyclinder.
Answer» 3.5 is height and radius is 7 cm TSA = 462 cm2\xa02 = 2πrh + 2πr2LSA = 1/3 of TSA= 1/3 462 =\xa0154 =\xa02πrh462 = 154 + 2πr2462 = 154 + 2 x 22/7 x\xa0r2462 - 154 = 2 x 22/ 7 x\xa0r2308 x7\xa0=r22 x 22 It\'s upon 2 into 22therefore\xa0r2\xa0= 49r = 7LSA = 2TSA = 462 cm2\xa02 = 2πrh + 2πr2LSA = 1/3 of TSA= 1/3 462 =\xa0154 =\xa02πrh462 = 154 + 2πr2462 = 154 + 2 x 22/7 x\xa0r2462 - 154 = 2 x 22/ 7 x\xa0r2308 x7\xa0=r22 x 22 It\'s upon 2 into 22therefore\xa0r2\xa0= 49r = 7 cmLSA = 2πrh\xa0154 = 2 x 22/7 x 7 x hh =\xa03.5 cmvolume =\xa0πr2h 22/7 x 7 x 7 x 3.5 =\xa0539 cm3
