3.14 square cm
The radius will stay as 1cm but the area of a circle is: pi times radius squared
2cm; the diameter of a circle is twice its radius.
The area of a circle is calculated from the formula Pi x r2 . A 1cm diameter circle has a radius of 0.5cm, thus it has an area of 0.785cm2
The area of a circle of radius 21 is 1386
The area of a circle with a radius of 14.4 is 651.4
The radius will stay as 1cm but the area of a circle is: pi times radius squared
The radius of a 1cm circle is 0.5cm. The radius is the distance from the center of the circle to any point on the circle's circumference. In a circle, the radius is always half the length of the diameter. Therefore, in this case, with a diameter of 1cm, the radius would be 0.5cm.

1cm
The radius is half the diameter = 1cm

The area of a circle with a radius of 14.4 is 651.4
Area of a circle = pi*radius squared
The area of a circle of radius 21 is 1386
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
