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

Answer:

The volume of the ball is $V=2,304\pi\ cm^{3}$  or  $V=7,234.56\ cm^{3}$

Step-by-step explanation:

we know that

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

$V=\frac{4}{3}\pi r^{3}$

we have

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

substitute

$V=\frac{4}{3}\pi (12)^{3}$

$V=2,304\pi\ cm^{3}$ ----> exact value of the volume

assume

$\pi =3.14$

substitute

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