The area of the sector is given by the equation, A = πr²(x / 360°) where x is the number of degrees in the figure. 25π ft² = (πr²)(60/360) The value of r is 12.25 ft. Then, we use this value to calculate for the circumference of the sector. C = 2πr(x/360) Substituting, C = 2π(12.45)(60/360) C = 12.83 ft³
