For an arc length s areas of sector A and central angle thet

For an arc length s, areas of sector A, and central angle theta of a circle of radius r, find the indicated quantity for the given value. A = 72.4 mi^2, r=72.4 mi, theta = ? theta almostequalto radian (Do not round until the final answer. Then round to three decimal places as needed.)

Solution

given A=72.4 ,r =72.4

A=(1_/2) r²

=>72.4=(1_/2) *72.4²

=> =2_/72.4

=> 0.028 radian
