CENTRAL ANGLE: <span>There are 32 passenger cars, so you want an angle equal to 1/32 of the full circle. </span> <span>The full circle in degrees is 360°, but you want radians. </span> <span>The full circle in radians is 2π. </span> <span>2π / 32 </span> <span>= π/16 radians </span> <span>ARC LENGTH </span> <span>The arc length would be 1/32 of the full circumference. I know you already asked and got answers for the full circumference. Divide that by 32. </span> <span>AREA OF SECTOR: </span> <span>Ditto on this. You have the full area from a prior question. Now just divide it by 32</span>
