Number 9 need help mathhh

Sergio039 [100]

Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3

<h3>How to get the volume of the sphere?</h3>

For a sphere of radius R, the volume is given by the formula:

$V = (\frac{4}{3})*3.14*R^3$

In this case, we can see that the diameter is 9 cm, then the radius is half of that:

R = 9cm/2 = 4.5cm

Now that we know the radius, we can replace it on the volume formula to get:

$V = (\frac{4}{3})*3.14*(4.5cm)^3 = 381.51 cm^3$
