Cherry Pie is delicious.
C= πd
Easy. Just divide the circumference by Pi (about 3.1416) to get the diameter.
C = pi*d Remember the circle eq'n To find 'd' we algebraically rearrange. to d = C/pi
Easy. Multiply the diameter (8 yards) by Pi (about 3.1416). The result is the circle's circumference:8 x 3.1416 = 25.1328 yards circumference
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
You need to know the radius first. Next you simply double the radius to get the diameter and then multiply that by pie and you have now worked out the circumference of your circle :)
find the radius of a circle with circumference of 42.1
easy pi 3.141592654 or 3.14 times the diameter then divide by four first you find the entire circumference then cut into halves or quarters
The circumference of a circle is the length of the circle's perimeter.
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
Diameter of a circle = circumference/pi
circumference of a circle = 2piradiuis or diameter*pi
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
