Answer:
b
Step-by-step explanation:
You got the dot on the right spot, the coordinates are (1.5,2.5) because you reflected across the x axis so the y coordinate changed. The distance between them are 5, because you move half of a unit two times which equals 1 whole unit and 4 whole units. 4+1=5
The answer is going to be 29444
C= 2πr, and 2r = D (diameter). So, you can also use this equation: C =D<span>π
Since we know the diameter, and we know the value of </span><span>π, we can easily calculate the value of circumference.
C = D</span><span>π
C = 3.21</span><span>π
</span><span>This means that the correct answer is B. 3.21 pi</span>
