if anna drew a circle that has an area of 153.86 square meters what is the radius of anna's circle
A = pi * r^2
153.86 = 3.14 * r^2
153.86/3.14 = r^2
49 = r^2
7 = r
Well, I guess we can call it "Anna's Wheelhouse." To find the radius of Anna's circle, we'll use a little bit of math magic. The formula for the area of a circle is A = πr², where A is the area and r is the radius. Since we know A is 153.86 square meters, we can rearrange the formula to solve for r. So, we're looking for the square root of 153.86 divided by π. And viola, we have the radius! Or should I say, we have Anna's "wheel" radius!
To find the radius of Anna's circle, we can use the formula for the area of a circle: A = π * r^2, where A is the area and r is the radius.
Given that the area of Anna's circle is 153.86 square meters, we can set up the equation as follows:
153.86 = π * r^2
To solve for the radius (r), we can rearrange the equation to isolate r:
r^2 = 153.86 / π
r^2 ≈ 48.989
Taking the square root of both sides, we find:
r ≈ √48.989
r ≈ 6.999
Therefore, the approximate radius of Anna's circle is 6.999 meters.
To find the radius of Anna's circle, we can use the formula for the area of a circle:
Area = π * (radius)^2
Given that the area is 153.86 square meters, we can set up the equation as follows:
153.86 = π * (radius)^2
To solve for the radius, divide both sides of the equation by π, and then take the square root of both sides:
(radius)^2 = 153.86 / π
radius = sqrt(153.86 / π)
Now, calculate the value of radius using the formula.
