While finding the sq.root of slant height (formula- l=root of h^2+r^2) in cone/frustum i'm getting a non-perferct square number..how to find the square root of that number then???
You can use the value of the slant height as it is.
for example: If you get the value of slant height as x
Use it as x. You can give the final answer in the terms of square roots.
Or else, you can find the square root of the number upto 2 decimal places by the long division method.
