If the spherical water balloon is filled with 113 milliliters of water, what is the approximate radius of the balloon

Volume of the balloon is 113 ml=0.113 liters

but 1 liter = 1000 cm^3

therefore the volume of the balloon in centimeters will be:

1000 (0.113)

=113 cm^3

hence the radius of the balloon will be calculated as follows;

v=4/3πr³

plugging our values in the formula we get:

113=4/3πr³

solving for r we get

r=2.999~3 cm
