Answer: I think the heat is retarding their maturity! Try pulling one of the radishes to see how large it has grown. If they are at least the size of a dime you can harvest them. If you leave them in the ground too long they can become woody or have hollow centers. As for the broccoli, they should have develop some stalks by now. If not, I'm afraid you'll just have to be a little more patient with your plants. Hope they do something soon!
