Trig

 Do not round any intermediate computations. Round your answer to the nearest tenth. || || || The area of a sector of a circle with radius  and central angle  is as follows. || || ||  ||  || || ||  || || Note that for this formula,  //must// be in radians. For our problem, the radius is and the central angle is  radians. Since the central angle is given in radians, we can apply the formula. > Rounding to the nearest tenth, we get.
