| December 28, 2020 | education
s = 4 * n (pi) * R ^ 2 (radius squared)
there is a property
The area ratio is equal to the square of the similarity coefficient
In this case, it is equal to 10 (already squared)
We get that the coefficient squared is 10, which means that the similarity coefficient itself is equal to the root of 10
