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 to find area of a circle?
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a circle...
How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
What is the area of a circle if you are only given the radius?
you take the radius, square it, then multiply it by 3.14 and there is the area
Does the area of a circle depend on the radius?
Yes. To get the area, you take the radius, square it, and multiply that by Pi, so it is the only variable and does affect the circle's area.
What the formula to take the are of a circle?
the area of a circle = pi times the (radius)squared
What is the area of a 6 dia circle?
Area = pi * radius^2. radius = diameter / 2, so radius of this circle is 3.Area = 9 * pi (take your favorite value of pi: 3.1416....)
What is the diameter of a circle when the area of the circle is 254.34?
Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18
How do you find the radius of a circle when the area is given?
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
What is the area to a half circle that is 22 feet in diameter?
area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2
How do you find the diameter if you have the area of a circle?
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
What is the radius of a circle whose area is 616 square meters?
Well, isn't that just a happy little question! To find the radius of a circle when you know the area, you can use the formula A = πr^2. In this case, the area is 616 square meters, so you can plug that in and solve for the radius. Just remember to take a deep breath, trust in your math skills, and enjoy the process of finding the radius of this circle.
How do you find the radius with the area given to you the area?
The area of a circle is A=πr2, so the radius is r = √(A/π). Divide the area by pi and then take the square root.
