Evaluate the integrals below by interpreting it in terms of areas. In other words, draw a picture of the region the integral represents, and find the area using geometry. 1 . 32 - x dx 2 . Vb2 - x2 dac = 3. Vb2 - ac2 + 3dx Hint: For Part c., note that y = Vb - x + 3 is the graph of y = Vb2 - x shifted up 3 units
