Answer:

V = 4186.67 in^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We need to know the radius

r = d/2 = 20/2 = 10

V = 4/3 (3.14) (10)^3

V =4186.66666666

Rounding to the nearest hundredth

V = 4186.67 in^3

Answer:

V ≈ 4186.67

Step-by-step explanation:

The formula for the volume of a sphere is [tex]\frac{1}{6} \pi d^{3}[/tex] where,

d = diameter

[tex]\pi[/tex] = 3.14....

We know that the diameter of the light sphere is 20in and so we plug it into d to get our answer.

[tex]\frac{1}{6} (3.14)(20)^{3}=4186.666667[/tex]
