Since the formula for circumference is 2 pi r, it will be 34.5pi as the radius is half the diameter. *however this is in the form of pi. If pi was in 3.14, then the answer would be 106.33Find the perimeter of the sector below, where the angle is in radians. The sector has a central angle of 4.8 radians and a radius of 17 ½ inches. The perimeter of a sector, where the angle is in radians is: \[ P = 2r + L \] \[ L = \theta r \] where P is the perimeter, L is the arc length, θ is the central angle and r is the radius of the circle....
