Question

Find the volume of a sphere with a diameter 40 cm in length. Approximate pi as 3.14 and round your answer to the nearest tenth. A. 5,026.5 cm3 B. 33,493.3 cm3 C. 42,090.0 cm3 D. 268,082.6 cm3

Answer 1

Option B.
`33,493.3\ cm^(3)`

Explanation:

we know that

The volume of the sphere is equal to

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

we have

`r=40/2=20\ cm` ----> the radius is half the diameter

`\pi=3.14`

substitute the values

`V=(4)/(3)(3.14)(20)^(3)=33,493.3\ cm^(3)`
