A cylindrical pop can has a volume of 355ml. Determine, to the nearest 0.1m, the diameter of the can if the height is 12.0cm

Question

 Don't understand to the nearest 0.1cm would appreciate explanation

Answer 1

Volume of Cylinder = πr²h

 

              355  = πr²12

 

              29.58 = πr²

    

              29.58/3.14 =r^{2 ________________(π=3.14)}

               9.416 = r²

 

               3.06 =r

r= 3.06 cm=0.036m
