A sphere and a cylinder have the same radius and height. The volume of the cylinder is 120 cubic inches. A sphere with height h and radius r. A cylinder with height h and radius r. What is the volume of the sphere? A.40 cubic inches B 90 cubic inches. C 160 cubic inches D 360 cubic inches

Respuesta :

Answer:

Option C. 160 [tex]inch^{3}[/tex] is the correct answer.

Step-by-step explanation:

We are given that height and radius of sphere and cylinder are same.

Radius 'r' and height 'h'.

We know that Volume of cylinder = [tex]\pi r^{2} h[/tex]

Also, h = r,

So, volume of cylinder = [tex]\pi r^{3} = 120\ inch^{3} ...... (1)[/tex]

Also, Volume of sphere = [tex]\dfrac{4}{3} \pi r^{3}[/tex]

Using equation (1), putting the value of [tex]\pi r^{3}[/tex]

[tex]\Rightarrow \dfrac{4}{3} \times 120\\\Rightarrow 160\ inch^{3}[/tex]

Hence, volume is sphere is option 3) [tex]160\ inch^{3}[/tex]
