With radius....? Well if 6km is the radius, then just use pi*r^2, in which case the answer is 113.1km squared. If 6km is the circumference, then use (c^2)/(4*pi), in which case the answer would be 2.86km squared. Then again, since you really weren't specific at all, to say "a 6km circle" may indicate that the diameter is 6km, in which case you would use pi*(d/2)^2, and then the area would be 28.27km squared.
Area = pi*radius squared
If it is a circle you are referring to the Area if the circle would be (pi)x(r^2) and the radius is 6 so the answer would be 36(pi)
113.0973355cm
area of circle is πr² (3.14)(6)² 3.14 * 36 = 113.45 cm² ■

A circle with a radius of 6 units has an area of 113.1 square units.
Area = pi*radius squared
Area of a circle: pi*radius*radius
Area of circle = PI * radius^2, so PI * 6^2 = 113.09733553 square feet.
If it is a circle you are referring to the Area if the circle would be (pi)x(r^2) and the radius is 6 so the answer would be 36(pi)
The area of a circle is calculated with the formula πr2, where r is the radius. Therefore, the area of a circle with radius 6cm would be π(6)2 = (36)π, or approximately 113.097 square centimeters.

The area of a circle is calculated as A = pi x r2
Area of a Circle = (pi)(r^2) Diameter = 2r If the diameter of the circle is 12, then the radius has to be 6. If the area of a circle is pi times the square of the radius, and the square of 6 is 36 (6x6), then the area of the circle is 36pi.
