Answer:
Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
Step-by-step explanation:
we know that
The volume of a sphere is equal to
[tex]V=\frac{4}{3}\pi r^{3}[/tex]
where
r is the radius
step 1
Find the volume of the golf ball
we have
[tex]r=2.1\ cm\\pi =3.14[/tex]
substitute
[tex]V=\frac{4}{3}(3.14)(2.1)^{3}=38.77\ cm^3[/tex]
step 2
Find the volume of the the softball
we have
[tex]r=4.2\ cm\\pi =3.14[/tex]
substitute
[tex]V=\frac{4}{3}(3.14)(4.2)^{3}=310.18\ cm^3[/tex]
step 3
Find the ratio of volumes
Divide the volume of the softball by the volume of the golf ball
[tex]\frac{310.18}{38.77}=8[/tex]
That means
Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
