2. TOYS A playground ball has a radius of
dalvyx [7]

Answer:

1767.1 inches cubed

Step-by-step explanation:

The volume of a ball, or a sphere, is: V=\frac{4}{3} \pi r^3 , where r is the radius.

Here, the radius is r = 7.5. So, plug in this value: V=\frac{4}{3} \pi *(7.5)^3=562.5\pi

562.5 pi is about 1767.1 inches cubed.

Thus, the volume is 1767.1 inches cubed.

Hope this helps!
