Question

ASAP What is the volume of a sphere, to the nearest cubic inch, if the radius equals 3 inches? Use π = 3.14. A. 101 in³ B. 210 in³ C. not given D. 96 in³

Answer 1

Answer: C. not given

Explanation:

formula for volume of sphere: V=(4/3)πr³

V=(4/3)πr³

V=(4/3)(3.14)(3)³

V=(4/3)(3.14)(27)

V=113 in³

Answer 2

C. Not given

V≈ 113 in³

Explanation:

The volume of a sphere can be found using the following formula.

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

We know the radius is 3 inches and we are using 3.14 for pi. Therefore, we can substitute
`3 in` in for
`r` and
`3.14` in for
`\pi`

`V= (4)/(3) *3.14* (3 in)^3`

Evaluate the exponent first.

(3 in)³= 3 in * 3 in * 3 in = 9 in² * 3 in = 27 in³

`V= (4)/(3) *3.14* 27 in^3`

Multiply 3.14 and 27 in³

`V= (4)/(3) * 84.78 in^3`

Multiply 4/3 and 84.78 in³

`V= 113.04 in^3`

Round to the nearest cubic inch. The 0 in the tenth place tells us to leave the 113 as is.

`V= \approx 113 in^3`

Since 113 cubic inches is not an answer choice given, the correct answer is C. not given
