A sphere is inscribed in a cube with a volume of 64 cubic inches. What is the volume of the sphere? Round your answer to the nearest whole number.

Respuesta :

Answer:

the volume of the sphere is

[tex]33.51 in^{3}[/tex]

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, sphere and cube.

Given data

Volume of cube v =   64 cubic inches

since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,

we know that volume of cube is expressed as

[tex]v= l*b*h[/tex]

[tex]v=l^{3}[/tex]

[tex]64= l^{3}[/tex]

[tex]l= \sqrt[3]{64}[/tex]

[tex]l= 4 in[/tex]

also diameter d=length l

Diameter d=  [tex]4in[/tex]

Radius r =  [tex]\frac{d}{2}[/tex]= [tex]\frac{4}{2}[/tex]= [tex]{2 in}[/tex]

Height h=[tex]4in[/tex]

we know that the volume of a sphere is given by

[tex]v= \frac{4}{3} \pi r^{3}[/tex]

substituting into the formula we have

[tex]v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}[/tex]
