The image above is a **hemisphere** with a radius of 5.

To compute the centroid or centre of gravity of a hemisphere. You need one essential parameter and this parameter is the **radius of the hemisphere** (r).

The formula for calculating the centroid or centre of gravity of a hemisphere is:

C.G. = ^{3r} / _{8}

Where

r = Radius of the hemisphere

As always let us try and solve an example:

Find the centroid or centre of gravity of a hemisphere where the radius is 5 cm.

From the formula this implies that:

r = Radius of the hemisphere = 5

C.G. = ^{3(5)} / _{8}

C.G. = ^{15} / _{8}

C.G. = 1.875

Therefore, the centroid or centre of gravity of the hemisphere is 1.875.

Nickzom Calculator – **The Calculator Encyclopedia** is capable of calculating the centre of gravity of a hemisphere at a distance from its base measured along the vertical radius.

To get the answer and workings of the **center of gravity** or **centroid **of a hemisphere using the **Nickzom Calculator – The Calculator Encyclopedia. **First, you need to obtain the app.

You can get this app via any of these means:
