How do you find the radius of the circle if you know the area?
Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).
Find the radius for a circle with the equation x2 plus y2 equals 9?
Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
When you are given pi of a circle how do you find the radius and diameter?
you cant: pi is the same for any circle - 3.1415... the diamter or the radius has to be given diameter divided by two equals the radius the radius times two equals the diameter
What is the approximate area of a circle with a radius of 3 feet?
Area of a circle equals pi (~3.14) multiplied by the radius squared. So to find the area of that circle your equation is (3.14)(3)^2 which equals approximately 27.
Find the diameter of a circle with this measurement equals 10.4 in?
It depends on what "this measurement" refers to: the radius, circumference, length of arc with a known angle.
How do you find out the circumfrance of a circle?
To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
What is the diameter of a circle with this measurement r equals 10.4 in?
Diameter is two times the radius, in our case the radius is 10.4 inches, Can you now find the diameter. I am sure you can, good luck!
How do you find the radius of the circle if you know the area?
Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).

What is the approximate area of a circle with a radius of 3 feet?
Area of a circle equals pi (~3.14) multiplied by the radius squared. So to find the area of that circle your equation is (3.14)(3)^2 which equals approximately 27.
Measuring to the center of a circle?
The easiest way to find the radius (measurement from the outside to the center of a circle) is to measure the diameter and divide by 2.
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
What is the area of a circle with a radius of 4.4?
To find the area of a circle based on its radius, multiply its radius squared by pi. Don't forget to square the radius before multiplying by pi, based on rules of BODMAS where you find powers of numbers before you multiply them.In this instance, (4.4 x 4.4) = 19.36. Multiplying this by pi gives us, accurate to two decimal places, 60.82. Don't forget to include the appropriate measurement. If the original measurement of the radius of the circle was in centimetres, then the area should be expressed in square centimetres. If the original measurement of the radius was in inches, then the area should be expressed in square inches.
How do you find the circumference of a circle when you know the area?
OK, SO to find the area of a circle, you find the radius (half of the diameter), and fit it into the equation πr2=A where r equals radius and A = area. The perimeter of a circle is π multiplied by the diameter. π is ≈ 3.1415296.
