Answer:
342.24 units²
Step-by-step explanation:
The area of one of the 8 triangular sections of the octagon is ...
A = (1/2)r²·sin(θ) . . . . . where θ is the central angle of the section
The area of the octagon is 8 times that, so is ...
A = 8·(1/2)·11²·sin(360°/8) = 242√2
A ≈ 342.24 units²
First, do 36/12 to find out how many laps you can run in a certain amount of minutes. It is 1 laps per 3 minuted. Then, do 3 times 20 because 60 minutes is in an hour. Then, 1 times 20 is 20. 20 laps is the correct answer.
The ratio is 3:10. 18/6=3 and 60/6=10
