Question

Find the volume of the sphere. Use 3.14 for π. Round to the nearest tenth.

Question 3 options:


A. 3,589.5 m3


B. 2,692.2 m3


C. 897.4 m3


D. 377.8 m3

Answer 1

Answer : The correct option is, (A)
`3589.5m^3`

Step-by-step explanation :

Formula used to calculate the volume of sphere is:

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

where,

V = volume of sphere = ?

r = radius of sphere =
`(Diameter)/(2)=(19m)/(2)=9.5m`

Now put all the given value in the above formula, we get:

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

`V=(4)/(3)* 3.14* (9.5)^3`

`V=3589.5m^3`

Therefore, the volume of the sphere is,
`3589.5m^3`

Answer 2

`3589.5\ m^(3)`

Explanation:

Given:

A sphere with diameter = 19 m

Radius of the sphere =
`(19)/(2)=9.5\ m`

Formula for volume of a sphere:

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

`V=(4)/(3)*\pi*(9.5)^(3)`

`V=3589.5\ m^(3)`

(After rounding off to nearest tenth)
