The angle in the diagram is 90 degrees, while the circumferential angle is 360 degrees, so 1/4 of the circle is blank, and the shaded region is 3/4 of the circle. The area of the circle is pi*r^2=36pi cm^2. While the region is only three quarters of it, so the area is 3/4*36pi=27pi cm^2.
Answer: B
Step-by-step explanation:
You can see that if you were going to cut the graph down the middle, if would be symmetrical.
The dimensions in the given should have the same unit in order for us to do mathematical operations with them. 3.5 km when converted to meters become 3500 m. The problem asked for the tiger's displacement, that is the distance from his starting point to his final position. This is equal to 1,250 m subtracted from 3500 m. Thus, the answer is 2250 meters.
