What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
What is circumference and diameter and radius?
The circumference is the distance AROUND a circle. The diameter is the distance ACROSS a circle. The radius is the the distance FROM THE CENTER of the circle (same thing as one-half of the diameter).
Is the circumference and the diameter the same thing?
Circumference is the perimeter of a circle Diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle
What is the diameter of a circle if the circumference is 80 -?
Diameter of a circle = circumference/pi
Why the value of pi is constant?
The value of pi is constant. It is calculated by dividing the circumference of a circle by its diameter. As the circle's circumference grows, the diameter grows at the same rate, proportionally. This means that the circumference divided by the diameter (if measured precisely) will always yield pi. If it does not, it is not a perfect circle. The ratio between the circumference and the diameter of a circle will always stay the same, no matter how you change the size of the circle.
