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!

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
Find the area of the circle shown with radius r equals 5 m?
25 pi sqm
What is the circumference of a circle if the radius is 6?
You have to find the diameter, 12, then you have to multiply that by 3.14 or pi... which equals 37.68.
