Sphere and Hemisphere


A Sphere is a three-dimensional round solid figure with every point on its surface equidistant from its centre.

where r is the radius of the sphere,

Diameter (d) = 2r

Surface area(S) = 4 π r²

Volume(V) = 4/3 π r3


Hemisphere means half of a sphere.

Lateral Surface area = 2 π r²

Total Surface area(S) = 3 π r²

Volume(V) = 2/3 π r3
