The circle below with center C is divided into 8 equal slices. Central angle LACB intercepts AB, forming the shaded sector. Complete the statements below. Give your answers as exact values, not decimal approximations. So, m AB = (a) Find the ratio of the area of the sector to the area of the circle. Area of sector Area of circle 0 0°. (b) From the figure we see that m ZACB=45°. The measure of LACB is undefined O 45° This gives the following equation. m AB 360° Area of sector Area of circle (c) Choose the equation that is true. Area of sector Area of circle = m AB A O Area of sector = O Area of sector = B mAB 360° m AB 360° 360° mAB --8a²² ·π₂.² the measure of AB. (d) Using for the area of the circle, choose the equation that gives a formula for the area of the sector. Area of sector Area of circle Area of sector Area of circle =8- O Area of sector mAB 360° 360° mAB m AB 360° -π/² Area of sector = m AB-²2² olo
