Answer:
All work but I’d pick the 3rd one
Step-by-step explanation:
$200 - 20% savings equals $160 total price
Tax is 6.5%
160X.065 = $10.40 for tax
The area of the sector is
.. Asector = (1/2)r^2*θ = (1/2)*(8.35 ft)^2*(π*260°/180°) ≈ 158.195 ft^2
The area of the triangle is
.. Atriangle = (1/2)r^2*sin(θ) = (1/2)*(8.35 ft)^2*sin(100°) ≈ 34.332 ft^2
The shaded area is
.. A = Asector +Atriangle
.. = 158.195 ft^2 +34.332 ft^2
.. ≈ 192.5 ft^2
48 it is counting up by odd numbers (3,5,7,9,11, 13
