Find the volume of each sphere. round to the nearest tenth.. volume v=4/3 1. 40 mm 2. 22 in 3. 7 cm 4. 34 in 5. 48 mm 6. 9 in 7. 6.7 ft 8. 12 mm

The complete question is
Find the volume of each sphere for the given radius. Round to the nearest tenth

we know that
[volume of a sphere]=(4/3)*pi*r³

case 1) r=40 mm
[volume of a sphere]=(4/3)*pi*40³> 267946.66 mm³> 267946.7 mm³

case 2) r=22 in
[volume of a sphere]=(4/3)*pi*22³> 44579.63 in³>  44579.6 in³

case 3) r=7 cm
[volume of a sphere]=(4/3)*pi*7³> 1436.03 cm³>  1436 cm³

case 4) r=34 mm
[volume of a sphere]=(4/3)*pi*34³> 164552.74 mm³> 164552.7 mm³

case 5) r=48 mm
[volume of a sphere]=(4/3)*pi*48³> 463011.83 mm³> 463011.8 mm³

case 6) r=9 in
[volume of a sphere]=(4/3)*pi*9³> 3052.08 in³> 3052 in³

case 7) r=6.7 ft
[volume of a sphere]=(4/3)*pi*6.7³> 1259.19 ft³> 1259.2 ft³

case 8) r=12 mm
[volume of a sphere]=(4/3)*pi*12³>7234.56 mm³> 7234.6 mm³

There is 240 red cars and there is 400 blue cars because 240/3=80 and 80*5=400
