Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40

The area of the square cannot be 400 centimetres - it must be 400 square centimetres.If the area is 400 sq cm, then each side is sqrt(400) = 20 cm.
Well, honey, to find the side length of a square with an area of 400 cm², you take the square root of the area. So, the square root of 400 is 20. Therefore, the side length of the square is 20 cm. Hope that clears things up for ya!
If a circle has area of 400 square units then its radius is: 11.25 units.
the area of the circle is increased by 400%
r = sqrt(400/pi) = 11.3 cm
400 pi
Using 3.14 as Pi the area of circle is: 1256.0
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
Area = pi R2 = 400 pi = 1,256.64 square inches
Using 3.14 as Pi the area of circle is: 1256.0
To find the radius of the circle, we first need to determine the radius of the sector. The area of a sector is given by the formula A = 0.5 * r^2 * θ, where A is the area, r is the radius, and θ is the central angle in radians. In this case, the central angle is 400 degrees, which is approximately 6.98 radians. Plugging in the values, we get 300 = 0.5 * r^2 * 6.98. Solving for r, we find that the radius is approximately 7.67 cm.
pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
area circle = π × radius² = π × (400 miles)² = 160000π sq mi ≈ 502655 sq mi
