You have 3 circles each with radius 1. They are externally tangent to each other, and internally tangent to a larger circle. Determine the radius of the larger circle. Round your answer to 2 decimals.
So... three circles basically side by side? 2 inches wide.. inside a big circle. right? I barely passed geometry and trigonometry. i was better at algebra. Okay so the three circles would make a diameter of 6? so the radius is 3? no thats not right, I don't know, sorry.
