They are: circumference/diameter = pi and circumference/2*radius = pi
well you can divide the circumference by pi (3.14) and it will always give you the diameter or you could measure it.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
to find the area of a semi circle measure the length of the straight edge, divide by 2, square it and multiply by pi. This will give you the area of the circle. To get the area of the semi-circle divide your answer by 2
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
Divide the circumference by pi, and that will give you the diameter.
Measure the diametre of the circle and divide by two to give the radius.
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
