<u>Given</u>:
Given that the diameter of the hemisphere is 12.6 cm
The radius of the hemisphere is given by

We need to determine the volume of the hemisphere.
<u>Volume of the hemisphere:</u>
Let us determine the volume of the hemisphere.
The volume of the hemisphere can be determined using the formula,

Substituting the values, r = 6.3 and π = 3.14, we have;

Simplifying the values, we have;


Dividing, we have;

Rounding off to the nearest tenth, we get;

Thus, the volume of the hemisphere is 523.5 cm³
