Question

Find the volume of this sphere.Use 3 for TT.VCarV- [?]ft3~ft --V = ar3=Hint: The radius (r) is1/2 of the diameter.

Answer 1

Looking at the image, the diameter of the sphere is equal to 6 ft.

Since the radius is half the diameter, the radius is equal to 3 ft.

Now, using r = 3 in the volume formula, we have:

`\begin{gathered} V=(4)/(3)\pi r^3 \\ V=(4)/(3)\cdot3\cdot3^3 \\ V=108\text{ ft}^3 \end{gathered}`

Therefore the sphere volume is 108 ft³.
