Can you do number 1 and 2 show all work to make sure rounded results with uncertainty ?

A. Error Propagation Exercises 1. Suppose you measure the diameter of a circle to be (12.34 + 0.05) cm. Calculate the circumference and area of the circle. State your final correctly rounded results with uncertainty. Show your work. (Note: It is recommended that you first write the formulas for C and A in terms of the diameter instead of the radius.) LS Circumference: Area: C = A = 2. Suppose x and y have the following measured values. Calculate A and B. State your final correctly rounded results with uncertainty. Show your work. x = (7.00 +0.05) cm y = (9.20+0.05) cm 4x3 A = 2xy B =
