Answer:
The area is approximately 1256.64 The circumference is approximately 125.66
Step-by-step explanation:
This is because to find the area of a circle you square the radius and multiply by Pi. To find circumference, you can multiply the Diameter (twice radius) by Pi.
Answer:

Step-by-step explanation:
The coordinates are:

The parallelogram is attached below.
To verify if these coordinates form a parallelogram, we show that:
Using Distance Formula




Since AB=CD; and AC=BD, the coordinates A, B, C, and D form the vertex of a parallelogram.
Answer:
Incomplete question.
Step-by-step explanation:
You've only provided the time.
Please provide the distance of the road.
The equation to find the circumference of a circle is ...
c = π × d
All we need to do to find circumference is to <em><u>multiply</u></em> the diameter (16km) by pi (π)
c = π × 16
c = 50.27
