3. About Spheres

4. Spheres
A sphere is a perfectly round
geometrical objects that is
3-dimensional with every point
on its surface equidistant from
its center

5. Spheres

6. Radius of a sphere
Radius
The radius of a sphere is
the distance from the
center to the surface.

7. Diameter of a sphere
Diameter
The diameter is always twice
the distance of the radius.

8. Surface Area
Surface area of sphere is the
product of the squares of its radius
by 4π.
Surface area =4πr2

9. Volume of a sphere
Volume of a
sphere= ⁴⁄₃πr3

10. Hemisphere
Section of a spherical shape by a plane
is called the hemisphere.

11. Curved surface area of hemisphere = 2πr2
Total Surface Area of hemisphere = 3πr2
Volume of hemisphere = ⅔πr3
Volume of Hemisphere
