What is the volume of a hemisphere with a radius of 39.4 ft, rounded to the nearesttenth of a cubic foot?

Sagot :

Given data

*The given radius is r = 39.4 ft

The expression for the volume of the hemisphere is given as

[tex]V=\frac{2}{3}\pi r^3[/tex]

Substitute the values in the above expression as

[tex]\begin{gathered} V=\frac{2}{3}\times3.14\times(39.4)^3 \\ =128034.51 \end{gathered}[/tex]

Thus, the volume of the hemisphere is V = 128034.51
