S = s(s +2h) = 24(24 +2*20) = 1536 . . . . square inches
Selection C is appropriate.
B is the correct answer :)
You can solve this problem and calculate the arc lenght, by applying the following formula:
s=θr
s: it is the arc lenght.
θ: it is the central angle (θ=2π/3).
r: it is the radius of the circle (r=10 inches).
When you substitute these values into the formula, you obtain the arc lenght (s):
s=θr
s=(2π/3)(10)
Then, you have that the value of the arc lenght is:
s=20.94 inches
1,400 inches or 116.7 feet
