Question

I am trying to put the answer 256 for this but I am getting it wrong I need help understanding why.

Answer 1

Given:

The diameter of the sphere is 8cm.

To find:

The volume of the sphere.

Step-by-step explanation:

The radius of the sphere is,

`\begin{gathered} r=(d)/(2) \\ =(8)/(2) \\ r=4cm \end{gathered}`

Then, the volume formula of the sphere is,

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

Plug in the value of radius for r, and we get

`V=(4)/(3)*3*[4]^3`

Evaluating the value we get,

`\begin{gathered} V=4*4^3 \\ V=256cm^3 \end{gathered}`

Final answer:

• The value that goes into the green box is 4.

,

• The volume of the sphere is 256 cubic cm.
