0.4x 0.4x 0.4 = (0.4)^3
Exponential form = (0.4)^3
Sinuar and radius of 16 are true
Well round to the nearest cent means to the nearest .01
So if the number is ex .0328
You round to .03
And if the number is ex .06831
You round to .07
Meaning if the number after .01 or .0_ is greater than 5 than you round up and if it's 4 or lower than you keep the number there
Sorry can't do much if this is an actual problem because you only said round to the nearest cent.
Try different problems and see wich two get you too 9 r5
