I need help to understand these.

The graph of f is shown below. Evaluate each integral by interpreting it in terms of areas. 1. 0 f(:c) d3: =0 Consider the graph of the function 9(3): The graph from a: = 2 to a: = 6 is a semicircle. Evaluate the following integrals by interpreting them in terms of areas: (a) [Meant] (b)6g(w)dw=C] (c)79(m)dm=C] Evaluate the integrals for at) shown in the figure below. The two parts of the graph are semicircles. Evaluate the definite integral: 7 4 dx -0 3Evaluate the definite integral: 4x dx -0 2Evaluate the definite integral 6 (8x + 5) dx 3Evaluate the integral by interpreting it in terms of areas: 15(8 5m)da: = C] Evaluate the following integral by interpreting it in terms of areas: fem-1w Value of integral = C] 8 8 7 If f(x) dx = 18 and f(x) da = 3.8, find f(x) dx. 7
