Question

What is the volume of a sphere with a diameter of 9.6 m, rounded to the nearest tenth of a cubic meter?

Answer 1

Answer:
`463m^3`

Explanation:

`Formula: V=(4)/(3)\pi r^3`

We don't have the radius but we do have the diameter. A diameter is twice the radius; therefore, I can divide the diameter by 2 in order to obtain the radius.

`(d)/(2)=(9.6)/(2)=4.8m`

Now plug this into the formula

`V=(4)/(3)(3.14)(4.8m)^3`

`V=(4)/(3)(3.14)(110.59m^3)\\ V=(4)/(3)(347.25m^3) \\V=463.00m^3`

Answer 2

463.2m^3

Explanation:

This is the right answer I got.
