The formula to find the arc length L is L = r*theta where r is the radius and theta is the central angle in radians (this formula will not work if theta is in degrees)
If the central angle is 1 radian, then theta = 1 and L = r*theta L = r*1 L = r So the arc length is the same as the radius
Since the distance around, or circumference, is 9, 622 ft. you need to use the formula for circumference to find the answer. So... 9,622=×diameter 9,622÷ = diameter diameter = <span>3062.77772486 feet</span>
