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:

$3589.5\ m^{3}$

Step-by-step explanation:

Given:

A sphere with diameter = 19 m

Radius of the sphere = $\frac{19}{2}=9.5\ m$

Formula for volume of a sphere:

$V=\frac{4}{3}\times\pi \times r^{3}$

$V=\frac{4}{3}\times\pi\times(9.5)^{3}$

$V=3589.5\ m^{3}$

(After rounding off to nearest tenth)

Answer 2

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

Step-by-step explanation :

Formula used to calculate the volume of sphere is:

$V=\frac{4}{3}\pi r^3$

where,

V = volume of sphere = ?

r = radius of sphere = $\frac{Diameter}{2}=\frac{19m}{2}=9.5m$

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

$V=\frac{4}{3}\pi r^3$

$V=\frac{4}{3}\times 3.14\times (9.5)^3$

$V=3589.5m^3$

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