Question

Determine the volume of a sphere with a diameter of 5 inches.Use 3.14 for Pi, and round your answer to the nearest inch.

Answer 1

65

Explanation:

formula = 4/3 * 3.14* r^3

= 4/3 * 3.14 * 2.5^3 (radius is half of the diameter)

= 65.44985

rounded to 65

Answer 2

`{ \bf{formular : \: { \tt{volume = (4)/(3) \pi {r}^(3) }}}} \\ { \tt{volume = (4)/(3) * 3.14 * {( (5)/(2)) }^(3) }} \\ { \tt{volume = 65.4 \: cubic \: inches}}`
