Question

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

Answer 1

r=2.999~3 cm

Explanation:

The Volume of the balloon is 113 ml=0.113 liters

1 liter= 1000 cm^3

the volume of the balloon in centimeters will be:

1000(0.113)

=113 cm^3

the radius of the balloon will be calculated as follows;

v=4/3πr³

113=4/3πr³

solving for r we get

r=2.999~3 cm

Answer 2

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
