Remember the circle equations.
A = pi r^2
C = 2 pi r = pi d ( Hence d = 2r)
Algebraically rarranging
r = sqrt(A/pi)
2r = d = 2(sqrt(A/pi))
Hence
d = 2(sqrt(28.26 / 3.141592...))
d = 2(sqrt(8.99543....)
d = 2(2.999239...)
d = 5.99847.... ~ 6 The answer!!!!!

Area of a circle is 2826 sq. cm, find its radius (Take π = 3.14)?
We apply the formula for the area of a circle to determine the radius of the circle: Area is equal to π * radius^2. Now that we know the area is 2826 square centimeters and that π is roughly 3.14, we can rewrite the formula to find the radius: 3.14 * radius^2 = 2826 Dividing 3.14 across both sides: radius^2 = 3.14 / 2826 radius^2 is around 900.63. To find the radius, take the square root of both sides: radius ≈ √900.63 radius approximately 30.04 centimeters
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
What is the radius of a circle with an area of 2826?
the formula for the area of a circle is pi times r squared (sorry this website does not work today for presenting this better) so 2826 = pi times r squared so dividing through on both sides bi pi gives you: 2826 divided by pi = r squared so r is the square root of (2826/ pi) 2826/pi = 899.5437384 so r is the square root of 899.5437384 = 29.99239468 r = 29.99 (to 2 decimal places)
