The area of a 6 unit circle is: 28.27 square units.
A 1.4-unit diameter circle has an area of 1.539 square units.
The circumference is 27.646 units.
The area of a square with side x is x2 SQUARE units. A circle with diameter 1 unit, has an area of pi/4 square units. Since the area of a square with side of 1 unit is 1 square unit, let us call the area of a circle of diameter 1 unit to 1 circular unit. That gives 1 circular unit = pi/4 square units. So a square with sides of x units = x2 units = pi*x2/4 or pi*(x/2)2 units.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
The area of a circle with a 22-unit circumference is 38.515 square units.
The area of a 6 unit circle is: 28.27 square units.
A 10.25-unit diameter circle has an area of 82.516 square units.
A 1.4-unit diameter circle has an area of 1.539 square units.
The circumference is 27.646 units.
Pi over 12 on a radian unit circle is a little more than a quarter of the circle. Radian units are an alternative to degrees.
A circle with a radius of 1 unit has an area of 3.14 square units.
The area of a square with side x is x2 SQUARE units. A circle with diameter 1 unit, has an area of pi/4 square units. Since the area of a square with side of 1 unit is 1 square unit, let us call the area of a circle of diameter 1 unit to 1 circular unit. That gives 1 circular unit = pi/4 square units. So a square with sides of x units = x2 units = pi*x2/4 or pi*(x/2)2 units.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
Circumference of a circle = 2*pi*radius or pi*diameter 7*pi = 21.99114849 units Therefore the circumference ot the circle is 22 units correct to the nearest unit.

Radian is the unit used to measure distances around a circle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
