Question

2. The diameter of a large blue beach ball is 16 inches. Calculate the volume of the blue beach ball to the nearest whole number.

Solve each problem. Use 3.14 for p.

Answer 1

2144

Explanation:

The formula for the volume of a sphere is:

`(4)/(3) \pi r^3`

So we can solve for that!

But wait, we have diameter, not radius!

Do not worry, I have a solution. The radius is half of the diameter, so we just halve the diameter to get 8 inches.

Now we plug in the values!

(Multiplication is communative, so it doesn't matter how we solve this as long as we do the exponent first)

8^3 = 512

3.14 * 512 = 1607.68

4/3 * 1607.68 = 2143.5

Rounding that to the nearest natural number gives us 2144.

Hope this helps!
