Plz mark my answer as brainliest
4πr^2 not 4πR^2 but thanks
both of them are the same yash
both are same. basically we should use"" r'' but many of books we find R
there is no rule like that
what if they give the radius as p??
r is a variable so any symbol can be used
mostly we Present small r thts why.....but both are correct
yeah both are correct
