Spheres
A sphere is a round solid figure where every point on its surface is exactly the same distance from the centre.



Volume of Spheres
To find the volume of a sphere, you need to multiply the radius cubed of the sphere by π then by 4 and divide the answer by 3.

Calculating the Surface Area of Spheres
To find the surface area of a sphere, you need to multiply the radius squared of the sphere by π and then multiply the answer by 4.
