Answer:
- Radius of the smaller sector = 12 cm
- Perimeter of the shape = 68 cm
- Angel = 47.72° (Approx)
Step-by-step explanation:
Computation:
Length of arc = Θ/360[2πr]
20 = Θ/360(2)(22/7)(24)
Θ = 47.72°
Angel = 47.72° (Approx)
Length of arc = Θ/360[2πR]
10 = [47.72 / 360][2][22/7][R]
R = 12 cm
Radius of the smaller sector = 12 cm
Perimeter of the shape = 20 + 24 + 24
Perimeter of the shape = 68 cm
