The parts will be hemisphere, given that they are equal.
Area of both hemisphere = 3πr² .
Area of both = 2 × 3πr² = 6πr².
Area of both hemisphere = 3πr² .
Area of both = 2 × 3πr² = 6πr².

HI
☺☺
RADIUS OF SPHERE = r
WE KNOW THAT SURFACE AREA OF SPHERE =4πR^2
AS IT IS DIVIDED INTO 2 EQUAL PARTS SO THEY ARE HEMISPHERES
AREA OF 2 PARTS =3πr^2+3πr^2
=
