The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
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
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
A circle with a radius of 135 units has an area of 57,255.53 square units.
A circle with a radius of 10m has an area of 314.16 m2
The area of a circle with a radius of 2m is: 12.566 m2
If the area of a circle is 40.7 the radius is: about 3.6 (3.599)
The area of a circle if the radius is 7yd is 153.9yd2
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
