Answer:
180 ft2
Step-by-step explanation:
First solve for the area of the trapzeoid using formula:
A= a+b/2xh
10+18x6/2
A= 84 ft2
Then solve for the rectangles B and C:
12x4= 48
48x2 (because theres two rectangles) which equals 96
Combine the two to get the total area:
96+84= 180
Answer:
K = (1/2)r^2(sin(θ) +θ)
Step-by-step explanation:
The area of the triangle to the left is ...
A1 = (1/2)r^2·sin(180°-θ) = (1/2)r^2·sin(θ)
The area of the sector to the right is ...
A2 = (1/2)r^2θ
so the total area of the blue shaded region is ...
K = A1 + A2 = (1/2)r^2·sin(θ) + (1/2)r^2·θ
K = (1/2)r^2(sin(θ) +θ)
