SPHERE :- Surface of which every point is the same distance from a fixed point known as the centre. From every aspect it has the same appearance. A sphere may be described by the rotation of a semicircle or circle, about its diameter.
FINDING SURFACE AREA OF SPHERE :-
FINDING VOLUME OF SPHERE :-
‘Hemi’ also means ‘half’. So When Sphere is Divided into two equal parts Each equal part is called Hemisphere
