A toy, in the shape of a sphere, has a radius of 5 inches. The toy is full of water. Approximately how many cubic inches of water are in the toy?
we have that
the volume of a sphere is equal to
[tex]V=\frac{4}{3}\cdot\pi\cdot r^3[/tex]we have
pi=3.14
r=5 in
Convert inches to cm
1 in=2.54 cm
5 in=5*2.54=12.7 cm
substitute the given values in the formula
[tex]\begin{gathered} V=\frac{4}{3}\cdot3.14\cdot12.7^3 \\ V=8,575.90\text{ cm3} \end{gathered}[/tex]Multiply by 2/3
8,575.90*(2/3)=5,717 cm3
answer is 5,717 cubic centimeters
