Question

A sports ball has a diameter of 12 cm. Find the volume of the ball.

Answer 1

The volume of a sphere is $\frac{4}{3}$πr³

If the diameter is 12 cm, divide that in half to get the radius, which is 6.

Now, just plug your variables into the equation for volume.

V = $\frac{4}{3}$(3.14)6³

V= $\frac{4}{3}$(678.24)

V= 904.32 cm³

Answer 2

Step 1: I drew a visual representation

Step 2: write the formulae for the volume of a sphere which is V=4*PI*r cubed all divided by 3. Refer to my image

Step 3: answer is 7234.56 cm cubed
