How do you do this question?

7√3 + 7π/6 ≈ 15.790

Step-by-step explanation:

First, find the intersection:

7 cos(2x) = 7 − 7 cos(2x)

14 cos(2x) = 7

cos(2x) = 1/2

2x = π/3

x = π/6

From the graph:

On 0 ≤ x ≤ π/6, 7 cos(2x) > 7 − 7 cos(2x).

On π/6 ≤ x ≤ π/2, 7 − 7 cos(2x) > 7 cos(2x).

So the integral is:

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
