Sphere and Hemisphere

SPHERE

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

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
