Volume and surface area of a hemisphere at a glance
A hemisphere is half of a sphere. The volume of a hemisphere is the amount of space within the hemisphere and the surface area of a hemisphere is the total area of the faces of the hemisphere.
To find the volume of a hemisphere, we find the volume of the whole sphere using the formula: V = frac{4}{3}πr^{3}, where r is the radius of the sphere. (The radius of a sphere is the distance from the centre of the sphere to the edge of the sphere and the diameter of a sphere is the distance from one side of the sphere to the other, through the centre of the sphere). We can half the volume of the sphere to find the volume of the hemisphere.
To find the surface area of a hemisphere, we find the surface area of the whole sphere using the formula SA = 4r^{2}. We can then half the surface area of the sphere to find the curved surface area of the hemisphere. To find the total surface area of a hemisphere, we then need to add the area of the circular base, found using the formula A = πr^{2}.
Sometimes we are asked to give an exact answer in terms of π. Other times we might be asked to round the answer to a given number of decimal places, to the nearest integer or to a given number of significant figures.
We usually use metric units for measurement and volume is measured in cubic units such as cm^3 and surface area in square units such as cm^2.
Looking forward, students can then progress to additional 3D shapes worksheets and other geometry worksheets, for example an angles in polygons worksheet or volume and surface area of spheres worksheet.
