Circumference: 2*pi*3 = 6*pi inches
Area: pi*3 squared = 9*pi square inches
To find the circumference of a circle with an area of 144π sq in, we first need to find the radius of the circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 144π sq in, we can solve for the radius: 144π = πr^2, r^2 = 144, r = 12 inches. The circumference of a circle is calculated using the formula C = 2πr, so for a circle with a radius of 12 inches, the circumference would be 24π inches.
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
A circle with a radius of 32 inches has an area of 3,216.99 square inches.
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
Area will be 28.27 inches2 Circumference will be 18.85 inches
2 inch radius = 12 9/16" circumference & an area of 12.56637 sq. inches.
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
Circumference is pi * r * 2. Area is pi * r2. In your circle, both r * 2 and r2 equal 4. Your radius is 2 inches.
Circumference = 2*pi*3 inches Area = pi*32 square inches
you have to quote the diameter or radius or circumference of the circle to calculate the area. If diameter 78.53. If radius 314.15. If circumference 7.95
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
C=14pi A= 98pi
Area = pi*r2 = 50.265 sq inches Circumference = 2*pi*r = 25.133 inches.
