The formula for finding the volume a hemisphere is given by

$V_{\text{hemisphere}}=(2)/(3)\pi r^3$

Given the diameter of 26inches, the radius would be

$\begin{gathered} \text{radius,r}=\text{diameter,d}(diameter,d)/(2)=(26inches)/(2) \\ r=13\text{inches} \end{gathered}$

Substituting for r in the volume of a hemisphere will give

$\begin{gathered} V_{\text{hemisphere}}=(2)/(3)*\pi*13^3 \\ =(2)/(3)*2197\pi\text{ cubic inches} \\ =1464.67\pi\text{ cubic inches} \end{gathered}$

Hence, the volume of the hemisphere is 1464pi cubic inches
