hartnn (hartnn):
if for 2nd , 4 is the radius, the above is correct......
i am confused on whether 4 is radius or diameter.
same for 3rd.
hartnn (hartnn):
IF 4 IS DIAMETER FOR 2nd,
2. lateral = 3*4*9=108
total = 108+24 =132
hartnn (hartnn):
total surface area of 3 is incorrect , 960+2*3*8*8 = ?
if 8 is diameter , 3. lateral = 3*8*20 =?
total = 2*3*16 + 3*8*20 = ?
hartnn (hartnn):
4. lateral , correct
total = 351 + 2*3*9*9 = ?
hartnn (hartnn):
5. absolutely correct

i think u need practice in finding total surface area, because almost all your total surface areas are incorrect ....
6. total = 2*3*12*12+2*3*12*40 = ?
