First, determine the diameter by dividing the circumference by Pi (about 3.1416): 13 / 3.1416 = 4.14. Next, divide the diameter by two to get the radius: 4.14 / 2 = 2.07. Finally, the formula for the area using the radius is:
So: A = 3.1416 x 2.072 (4.2849) = area of about 13.46 units2
The area of a circle with a circumference of 13 is: 13.45 square units.
The circle's area is about 13.45 square units.
Area is 13.449 square inches.
The circumference of a circle with a radius of 13 is: 81.68 units.
The radius of a circle with a circumference of 13 feet is: 2.069 feet.
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Circumference = pi*13 yards
The circumference of a 13-foot diameter circle is: ~40.84 ft
The circumference of a circle with a 13-inch radius is: 81.68 inches (r x 2 x pi = circumference).
The circumference is about 40.84 units.
2 x 13 x pi = 81.68 Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 2*pi*13 = 81.68140899
The circumference is about 81.7 feet.
