A circle with a radius of 3 cm has an area of 28.27 square cm.
A circle with a radius of 6 cm has an area that is about 113.1 cm. 3/4 of that is 84.825 cm
3.0
Area of a circle = pi x radius2 The area of a circle with radius 3 cm = pi x 32 = 28.27433388 = 28.3 cm2 (1 decimal place)
Its radius is the square root of 27 which is about 5.196 cm rounded to 3 decimal places.
A circle with a radius of 3 cm has an area of 28.27 square cm.
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
A circle with a radius of 6 cm has an area that is about 113.1 cm. 3/4 of that is 84.825 cm
Using 3.14 as Pi the area of circle is: 28.259999999999998
Using 3.14 as Pi the area of circle is: 379.94
Area = pi*4.52 = 63.617 square cm to 3 d.p.
Area = pi*272 = 2290.221 square cm to 3 dp
Area = pi*9.12 = 260.155 square cm to 3 dp
Area = pi*212 = 1385.442 square cm to 3 decimal places
