How do you find the area of a circle when the only information you have is the circumference?
Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
What is Circle formula from circle circumference to circle area?
Divide by pi then divide by 2 then square the number and then multiply by pi
How do you find the area of a circle using its circumference?
Divide the circumference by 2pi(3.14). That will give you the radius.Square the radius and multiply by piThat will give you the area.Calculate the radius by dividing the circumference by 2pi. Then square the radius and multiply by pi to get the area.
How do you find the circumference of a circle of you know the area?
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
How do you dind the area of a circle if you have the circumference?
C=2*pi*r A=pi*r^2 so you divide the circumference by 2*pi (~6.28), then square that and multiply by pi (~3.14) and that would get you the area of a circle i.e. if Circumference = 62.8 inches...you divide by 6.28 and get 10, then you square that (10*10=100), then you multiply by pi...100*3.14= 314 square inches.
What is the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
How do you find the area of a circle when the only information you have is the circumference?
Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
Does 3.14 stand for circumference?
3.14 is the approximate value of pi. Multiply the diameter of a circle by pi to get its circumference; multiply the square of the radius of a circle by pi to get its area.
How do you easily find the area and the circumference of a circle?
Area- square the radius of the circle and multiply it by pi Circm.- multiply the radius by 2 and then multiply that number by pi
What is circumference of a circle with 154 square inches?
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
What do you multiply the radius by?
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
What is Circle formula from circle circumference to circle area?
Divide by pi then divide by 2 then square the number and then multiply by pi
How do you find circumference of a circle?
Multiply the diameter by 3.14159 (Pi) to get the circumference multiply the diameter by pi. pi is 3.14159 * * * * * Depends on what information you have. You could multiply the area by 2/radius
How do you find the area of a circle when you are only given its perimeter?
The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.

How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
