Surface area of sphere is what referred to as Total surface area or lateral surface area because here the surface is curved everywhere.
[tex] \large{ \boxed{ \rm{ \orange{Surface \: area \: of \: sphere = 4\pi {r}^{2} }}}}[/tex]
Total surface area of other 3-D shapes:
- Cuboid = 2(lb + bh + hl)
- Cube = 4s²
- Cylinder = 2πr(r + h)
- Cone = πr(l + r)
- Hemisphere = 3πr²
Lateral surface area of these shapes:
- Cuboid = 2h(l + b)
- Cube = 6s²
- Cylinder = 2πrh
- Cone = πrl
- Hemisphere = 2πr²
