A circle with a radius of 3 meters has an area of 28.27 square meters.
18.84
3 meters, 1/2 of the diameter
It's half of the area of the whole circle...
If you mean area of a circle with a radius of 25 cm then it is:- Area = pi*252 = 1963.495 square cm to 3 decimal places
For a circle, A = pi*r2 where A is the area and r the radius. For an anuulus, A = pi*(R2 - r2) where R is the outer radius and r the inner radius. So, A = pi*(182 - 102) = 703.717 (to 3 dp)
Using 3.14 as Pi the area of circle is: 28.259999999999998
With regards to the area of a circle it is: pi*1.5*1.5 square meters
Using 3.14 as Pi the area of circle is: 12.56
Area: pi*1.52 = 7.069 square meters rounded to 3 decimal places
The area of a circle with a radius of 3 feet is: 28.27 square feet.
A circle with a radius of 3 cm has an area of 28.27 square cm.
Using 3.14 as Pi the area of circle is: 0.5024000000000001
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
A circle with a radius of 3 inches has an area of 28.27 square inches.
Assuming you are referring to a circle: the formula for the area is A = pi x radius squared. To solve for the radius, divide the area by pi, and take the square root.Since you want the diameter, you will then need to multiply the radius by 2.
Area = pi*radius squared
Area = 22/7*32 = 28.'285714' square meters and the decimals repeated
