Question

The volume of a spherical balloon with radius 2.6 cm is about 74 cm3. Estimate the volume of a similar balloon with radius 10,4 cm,

Answer 1

To find the volume of a similar ballon with radius 10.4 cm, we will simply take the proportion

Let v be the volume of the similar ballon;

`(74)/(v)=(2.6)/(10.4)`

Cross -multiply

`2.6v\text{ = 769.6}`

Divide both-side by 2.6
