The correct answer for the question that is being presented above is this one: "28 in^2."
We have to get the individual area of each surface.
A1 = 1*3*2 = 6
A2 = 1*3*2 = 6
A3 = 1*2*2 = 4
A4 = 2*3*2 = 12
Area = A1 + A2 + A3 + A4
Area = 6 + 6 + 4 + 12
Area = 28 in^2
If it's a square then sides equal to around 12-13 meters
Answer:
The central angle of the sector is 0.5 radian
Step-by-step explanation:
given;
radius of the circle, r = 80 mi
area of the sector, A = 1600 mi²
Area of sector is given by;
A = ¹/₂r²θ
where;
θ is the central angle (in radians) of the sector

Therefore, the central angle of the sector is 0.5 radian
