Egg Estimation ```Name: Joe Status: other Age: 15 Location: N/A Country: N/A Date: N/A ``` Question: How Can I work out the rough surface area of an egg with one of the most simple formulas you know which is still accurate? Please reply soon. Thankyou very much Replies: Hello, You can assume the egg to be spherical with a radius R. Area is then 4 x pi x R^2. If you take R to be the longest (shortest) radius of the egg, the surface area is over(under)estimated. You can use the average of the two, however, for a better approximation. I think it is best to use the geometric average R=Squarerootof(R1 x R2) (where R1 and R2 are the major and minor axes) instead of the arithmetic average (R=(R1+R2)/2). You can alternatively assume an ellipsoidal shape, but I do not remember the equation for its surface area.
