=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.
Surface area = 4*pi*radius2
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 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
