If you know the diameter or the radius then it's 2 times Pi times the radius or pi times the diameter. Pi is an irrational number usually shown as the Greek letter Pi (two upright strokes and one horizontal over the top) and is very approximately 22 divided by 7 or 3.14159

50.27 yards


What is the circumferenceof a circle if the diameter is 30m?

30 pi m


What is the circumferenceof a circle 13cm diameter?

What is the circumferenceof a circle if the area is 28 square meters?

Let the radius of the circle be r [m]. area of the circle = pi * r^2 circumference = 2 * pi * r given: pi * r^2 = 28 [m^2] Therefore, r = square root of (28/pi) = 2.99 [m]. circumference = 2 * pi * 2.99 = 18.76 [m]


How can you would you use the area of a circle formula to solve a problem?

-- If the problem gives you the radius, the diameter, or even the circumferenceof the circle, and asks you to find the circle's area, then the area-of-a-circleformula is exactly what you need.-- On the other hand, if the problem gives you the area and asks you to find theradius, or the diameter, or even the circumference of the circle, then you alsoneed to use the area-of-a-circle formula, and you also probably have to knowwhat you're doing.-- Finally, if the problem is talking about the amount of money earned in five yearswith compound interest, or the heat dissipated by a 47-ohm resistor with 10 voltsacross it, or the gravitational force on the Earth in the presence of a 10-kilogrammass located 1 meter off of the ground, or the most effective diplomatic approachto getting Iran's nuclear weapons program suspended, then the area-of-a-circleformula is completely useless, and can not help at all.

If chord AB measures 12mm and the radius of circle P is 10mm What is the distance from AB to P?

It's not clear from the question whether 'P' is the center of the circle, or maybe the circumference.The distance from the center to the midpoint of AB is 8 mm.The distance from the midpoint of AB the rest of the way to the circumferenceof the circle is 2 mm.
