ANSWER
[tex]Volume =623.3ft^3[/tex] to the nearest tenth.
EXPLANATION
The volume of a sphere is calculated using the formula;
[tex]Volume =\frac{4}{3} \pi r^3[/tex]
where [tex]r[/tex] is the radius of the sphere.
The radius was given as [tex]5.3ft[/tex] in the question.
We now substitute [tex]r=5.3[/tex] and [tex]\pi=3.14[/tex] in to the formula for finding the volume of the sphere to obtain;
[tex]Volume =\frac{4}{3} (3.14) (5.3)^3[/tex]
This implies that;
[tex]Volume =623.3ft^3[/tex]
