Yes the radius does affect the area of a circle. In fact to find the area of a circle people need to know the radius. The radius is half way between the middle of a circle to any of it's edges. The formula for the area of a circle is
pi*radius squaredYou must first find the square of the radius and multiply it by pi(3.14.) For more help go to Wikipedia.com and type circle.Yes. To get the area, you take the radius, square it, and multiply that by Pi, so it is the only variable and does affect the circle's area.
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.
