Question

The volume of a spherical balloon with radius 3.4 cm is about 165 cm3. Estimate the volume of a similar balloon with radius 17.0 cm.

Answer 1

we can use the formula of the sphere

`V=(4)/(3)\pi* r^3`

and replace the value of the new radious

`\begin{gathered} V=(4)/(3)\pi*(17)^3 \\ \\ V=(4)/(3)\pi*4913 \\ \\ V=(19652)/(3)\pi\approx20,579 \end{gathered}`

the volume of the new ballon is 20579 cm3
