Select the correct answer from each drop-down menu. in a circle with a radius of 7 feet, the radian measure of the central angle subtended by an arc with a length of 4 feet is . the area of the sector formed by the arc is square feet. assume π = 3.14, and round your answers to the nearest hundredth.

In a circle, the number of radians is proportional to the relative length of the arc, in comparison to the radius. We have that if we denote by x the radians, the following proportionality holds, relating angles and lengths:

because the total of angles in radians is 2pi and the total circumference is 2pi times the radius. Hence, by solving for x we get: x=4/7=0.57 rad

We also have that the area is proportional to the angles. The total are is . Hence, A=
