Question

Sheena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation?

v=1n24?(12)
ovo n.12?24)
v=1m24
v=112

Answer 1

The volume of the ball is
`V=2,304\pi\ cm^(3)` or
`V=7,234.56\ cm^(3)`

Explanation:

we know that

The volume of the sphere ( a ball) is equal to

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

we have

`r=24/2=12\ cm` -----> the radius is half the diameter

substitute

`V=(4)/(3)\pi (12)^(3)`

`V=2,304\pi\ cm^(3)` ----> exact value of the volume

assume

`\pi =3.14`

substitute

`V=2,304(3.14)=7,234.56\ cm^(3)` -----> approximate value
