Question

Beach ball has a diameter of 10 in what is the volume of air contained inside the beach ball

Answer 1

to find the volume of a sphere, you need the formula which is V=4/3(pi)r^3(r cubed). since radius equals to one-half of diameter. Since the beach ball's diameter is 10 inches, 10/2=5 <= radius. 5 cubed is 125 and 4/3 multiplied by 125 equals 166.67( i rounded to the tenths). Your volume will equal 166.67pi
( if you wanted in numbers than it will be around 523.438in cubed

Answer 2

The formula for volume of a sphere is
`(4)/(3) \pi r^(3)`
To get radius from diameter, we must divide it by 2. 10/2=5, meaning the radius is 5 in.
Now, we just need to plug the values into the equation.

`(4)/(3) \pi 5^(3) = (4)/(3) \pi 125 = 166.67 \pi = 523.61 in^(3)`
