Area of circle using 3.14 for pi: 3.14*5^2 = 78.5 square inches
314 sqmm
A circle with a radius of 10 meters has an area of 314 square meters.
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
S.A. = 4 pi r^2 Substituting 314 = 43.14r^2 Algebraically rearrange 100/4] r^2 = 314 / (4 * 3.14) r = sqrt[314/(4*3.14)] r = sqrt[ 100/4] r = sqrt[25] r = 5 inches The circumference of a sphere is a circle. Hence C = 2 pi r C = 23.145 C = 10*3.14 C = 31.4 inches.
The area of a circle equals the radius multiplied by itself, multiplied by pi. Pi rounded to the nearest hundredth is 3.14. If the radius is 10, multiply 10 by 10 and then multiply by 3.14. The area is 314. (Don't forget to write the units correctly cm2 etc)
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).

314 sqmm
The area is 314 cm2
Using 3.14 as Pi the area of circle is: 314.0
A circle with a radius of 10 meters has an area of 314 square meters.
A circle with a radius of 10 meters has an area of 314 square meters.
10 feet.
100pi, or approximately 314.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
3.14*r*r=area 3.14*100=314 or 100pi
