Let D be the region lying above the graph of y = |a|, outside of the circle x2 + y2 = 25, and inside the circle x2 + (y - 6)2 = 36. Then we can write 3x dA D Vac2 + 32 a c where F(r, 0) = b and Answer entry help: 1. a, b, c, d here may denote numbers, functions of 1 variable, or functions of 2 variables. 2. No blank spaces are allowed in the answer fields 3. If your answer a = Z please write only Z in the answer box. Note that a = is already written. Thus, if you put a = Z in the answer box, the system will read this as a = a = Z and will treat as a wrong answer. 4. Write theta for 0 Write v*z for v . z (multiplication of v by z ) Write tan(theta) for tan 0 (parenthesis are required) Write sqrt(z) for vz (parenthesis are required) Write Viz for vz Check
