How do you find the area of a circle with just the radis?
If you have the radius of the circle then just plug it into the equation which ispi x r2This equation is used to find the area of a circleSo if your radius is 5 then all you do is 52 and then multiply by piHope that helps.Jamz159
How do you find the circumference of a circle without knowing the radius and area?
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
How do you find diameter knowing the circumference?
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
How do you find out the the diameter of a circle if knowing the circumference?
Divide the circumference by the value of Pi - that will give you the diameter.
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.

How do you find the diameter of a circle knowing only the circumference?
to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
How do you find the area of a semi circle knowing the radius?
count the number of sides?
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
Why it is so important to know the area of a circle?
Knowing the area of a circle which is pi times radius squared will help you to find other properties of the circle

How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
How do you find the circumference of a circle knowing only the diameter?
Circumference of a circle: pi times diameter
What is a center coordinate of 2 points known circle?
Knowing two points on a circle does not define a unique circle, so it is impossible to find the centre of the circle as there are infinitely many centres possible.
