400 pi = 1,256.64 square inches (rounded)
Using 3.14 as Pi the area of circle is: 1256.0
1256 inches squared
radius = 20/(2*pi) = 3.183098862 inches
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
Area of a circle = πr² (remember that r or radius is exactly half of the diameter) Radius therefore = 40/2 = 20 inches Thus the Area = 3.14159 × 20 squared = 1256.636 square inches
Area = pi*r2 So r = 20 inch gives area = 1256.64 sq inches.
To find the radius of a circle with a circumference of 20 inches, you can use the formula for circumference: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 20 inches, you can plug this value into the formula: 20 = 2πr. Solving for r, you get r = 20 / (2π) ≈ 3.183 inches. Therefore, the radius of the circle is approximately 3.183 inches.
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
The radius of a circle is half the length of its diameter. Therefore, if the diameter of a circle is 20 inches, the radius would be half of 20, which is 10 inches. The formula to find the radius of a circle is radius = diameter / 2. So in this case, the radius would be 10 inches.
If the area of a circle is 20 square inches the diameter is: 5.046 inches.
15.707963267948965 square inches. I think.* * * * *That is a very accurate but very wrong answer.The correct answer is 314.159 sq inches (to 3 dp).******Yes, the correct answer is 314.159. Here's why:The area of a circle can be found by multiplying pi (3.14159...) by the square of the radius. (The radius of a circle is 1/2 the diameter)This 20" circle has a radius of 10", so its area is 3.14*10"*10"=314.159
