When you double the diameter, the circumference is also doubled.
If you double the circumference. the diameter like wise would double.
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
The circumference = pi x r2, and the diameter = 2r. So if you start with the circumference, you divide that number by pi (3.1416), then take the square root. What's left is the value of the circle's radius; double it to get the diameter.
The equation for a circle is PiD. The diameter is double the radius, so it is 7 yards in this case. The circumference is 7*PI. Which is approximately 21.98.
When you double the diameter, the circumference is also doubled.
As circumference = π x diameter and π is constant (≈ 3.14159), doubling the diameter will double the circumference.
If you double the circumference. the diameter like wise would double.
The circumference of any circle is (pi) x (diameter),and of course, the diameter is double the radius.
Double the radius.
Easy. First, double the radius to get the diameter. Next, multiply the diameter by pi (about 3.1416). The result is the circumference of the circle.
I would think it would double also. Say Circle A has a diameter of 1 inch and Circle B has a diameter of 2 inches. To get the circumference, you multiply the diameter by pi (3.14). So 1 x 3.14 = 3.14 so that is the circumference of Circle A. To get the circumference of Circle B you need to multiply 2 x 3.14 = 6.28. And 6.28 is twice 3.14 so I would think the circumference doubles.

Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
It'll more than likely double the circumference, too. BOOM.
Double the radius to 4.5 meters, which is the diameter. From there, multiply the diameter by Pi to get the circumference:4.5m x Pi = circumference of about 28.27 meters
