=4 * Pi * R * R When R= Radius of the ball Pi= 22/7
Calculate the area of the ball with a diameter of 12 metres
Surface area of a ball or a sphere = 4*pi*radius squared
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
To calculate the pressure exerted on a surface, the force acting on the surface is divided by the surface area. Mathematically, pressure = force / area.
surface area divided by volume
To calculate the pressure exerted on a surface, the force normal to the surface is divided by the surface area. The formula for pressure is pressure = force / area.
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
Surface area = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2
It depends on the shape whose surface area you are interested in.
The surface area of a sphere = 4*pi*radius2
