What is the circumference with a radius of 5?
Similarly, you may ask, what is the circumference of 5?
Assuming the circle diameter is equal to 5 ft, then the circle circumference is equal to pi×diameter or 3.14159×5 ft = 15.70795 ft or approximately 15.7 ft.
Subsequently, question is, what is the circumference of the radius is 7? Since the diameter d is equal to 2 times the radius r , the formula for circumference using radius is 2πr 2 π r . Substitute the value of the radius (r=7cm) ( r = 7 c m ) into the formula for the area of a circle. Pi π is approximately equal to 3.14 .
Also asked, what is the radius If the circumference is?
A circle's circumference is always twice that of its radius. Substitute radius for diameter in the equation Pi = c/d. The equation Pi = c/2r means that Pi (r) = c/2, so r = c / (2 Pi). The radius of a circle is therefore equal to c / (2 Pi) where c is the circumference of the circle.
What is the formula for circumference?
The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
