The question is stated as if in the presence of excessive background noise.
If we're talking about a circle, and if '1,017.36' is its area, then we can find the radius like this:
1,017.36 = pi R2
Divide each side by pi:
1,017.36 / pi = R2
Take the square root of each side:
R = sqrt( 1,017.36 / pi ) = 17.99544(rounded)
=====================================
We're guessing that the given radius was 18, and some arithmetic errors crept in
during the process of finding the area.
If the radius is 18, then
Area = pi R2 = 324 pi = 1,017.88 (rounded)
Working backward from 1,017.88, we would get 18.00004 for the radius.

How can you calculate the radius with the area given to you?
Area of a circle = pi x radius squared, so to get the radius, divide the Area by pi (3.14159), and then find the square root of that
What is the area of a square with radius 17 ft?
What is the area of a square with a radius of 17 ft
What is the area of a circle with a radius of 7 meters?
3850m is the area of the a circle whose radius of 7meaters
What is the radius of a sphere that has a surface area of 256?
The radius is 4.5135
What is the area of a circle if the radius is 5 cm?
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
How can you determine the area of a circle by using the radius squared and without finding the radius?
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
How do you find the radius of a circle if you already know the area?
The area of a circle equals pi times the radius squared (A = pi*radius2) where pi is 3.1416 So the radius is the square root of the area divided by 3.1416
How do you find the radius of a circle if you know the radius?
You already know the radius.
What happens to the area of a circle when the radius is triple?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
How do you get circumference from area of a circle?
Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)
What happens to the area of a circle when the radius is doubled tripled?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
How do you find the diameter of a circle if they give you the area?
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What is a radius square?
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
