4. Given a circle of radius 6 with the sector shaded as shown in the figure. (a) Find the angle \( \theta \) subtended at the center when arc length is \( s = 2\pi \). (b) Find the area of the sector formed by the arc \( s \). (c) Find the area of the triangle formed by the two radii \( r \). (d) Find the area of the shaded region. *** The figure shows a circle with radius \( r = 6 \). A sector is highlighted, with the angle \( \theta \) at the center and the arc length marked as \( s = 2\pi \). The two radii forming the sector meet the circle at the arc's endpoints. The shaded region is the area of interest. 3. Given \( f(x) = 4 \sin(2x - \frac{\pi}{2}) + 1 \) (a) Put it in standard form \( y = a \cos[k(x - b)] + v \). (b) Find the amplitude, period and crunch factor, the horizontal, and vertical shift. (c) Find the interval for one cycle, build a table of values and graph the function.
