Well, since the formula for the area of a circle is Pi (3.14) times the radius squared, you can use substitution to get an equation that looks like this: 3.14(102) ...which can be simplified to 3.14(100), which can be simplified to come up with the answer of 314 square units.
3850m is the area of the a circle whose radius of 7meaters
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
A circle with a radius of 11m has an area of ~380.13 m2
314 sqmm
The area is 314 cm2
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.
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
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
It is: the square root of (314/pi) = 9.997 units to 3 dp
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
