How do you find the circumfrance of a circle if you have the radius?
multiply the radius by two then pultiply that by pi
How do you get the radius of a circle from the circumfrance?
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
How do you find the circumfrance of a circle?
To start with, you try to spell them correctly. You either measure the circumference (not circumfrence)of a circle (not circl) or calculate it. Formulae for calculations will depend on what is known about the circle.
Find the area of the circle whose radius is 8 miles?
64pi (miles square)
How do you find the area of a circle whose radius is 12 centimeters?
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
How do you find the circumfrance of a circle if you have the radius?
multiply the radius by two then pultiply that by pi
How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
What is the circumfrance of a circle and how do you find it?
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
How do you find out the circumfrance of a circle?
To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
