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)

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
