r = sqrt(400/pi) = 11.3 cm
If a circle has area of 400 square units then what is the radius?
If a circle has area of 400 square units then its radius is: 11.25 units.
Area of a circle with 40 ft circumference?
To find the area of a circle with a circumference of 40 ft, first use the circumference formula (C = 2\pi r) to solve for the radius (r). Rearranging gives (r = \frac{C}{2\pi} = \frac{40}{2\pi} = \frac{20}{\pi}). The area (A) can then be calculated using the formula (A = \pi r^2), resulting in (A = \pi \left(\frac{20}{\pi}\right)^2 = \frac{400}{\pi}) square feet, which is approximately 127.32 square feet.
What is the circumference of a circle with an arc of 90 and an angle of 81?
90*360/81 = 400 units of length.
Find the area of a circle with the diameter of 40m?
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)

Find the circumference of a circle if the area is 400 Pi meters?
First we have to find the radius: pi*radius2 = 400*pi square meters Divide both sides by pi and then square root both sides: radius = 20 meters 2*pi*radius or pi*diameter = circumference 2*pi*20 = 40*pi meters
