With a ruler, Diamond determines the diameter of a golf ball to be 4.2 centimeters (a radius of 2.1 cm) and the diameter of a pr

Troyanec [42]

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

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

where

r is the radius

step 1

Find the volume of the golf ball

we have

$r=2.1\ cm\\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(2.1)^{3}=38.77\ cm^3$

step 2

Find the volume of the the softball

we have

$r=4.2\ cm\\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(4.2)^{3}=310.18\ cm^3$

step 3

Find the ratio of volumes

Divide the volume of the softball by the volume of the golf ball

$\frac{310.18}{38.77}=8$

That means

Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
