To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
OK, The circumference of a circle is 2 times pi (3.14) times the radius. SO the radius is = to circumference (5cm) divided by 2 times pi. 5 divided by 6.28 = .796 time 2 gives us a diameter of = 1.59 centimeters. We could also use Pi = cicumference/diameter therefore 3.14=5/x Multiply both side by x and 3.14 x = 5 Divide both sides by 3.14 and you get x= 5 divided by 3.14 which equals 1.59 cm
The formula for the circumference of a circle is 2πr, where r is the radius. We can rearrange this formula to solve for the radius: r = circumference / (2π) = 9.42 / (2 * 3.14159) = 1.5. Then, using the formula for the area of a circle (πr^2), the area is π * 1.5^2 ≈ 7.07 square units.
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
To find the area of a circle inscribed in a square, you can use the formula for the area of a circle (πr^2) and the properties of a square (all sides equal). Since the diameter of the circle is equal to a side of the square, you can find the radius of the circle by halving the side length of the square. Then, plug the radius value into the area of a circle formula to find the area.
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
Circumference is about: 44 Area is about: 153.94
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Area Diameter Radius Circumference
Circumference: multiply the diameter by pi (approximately 3.1416). Area: Divide the diameter by 2 to get the radius. Then use the formula area = pi x r2, where r is the radius.
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
The answer will depend on what information you have: radius, area, diameter.
Five is what, again? Radius, diameter, area?
