Area = Pi(radius)squared.
You only need the radius of a circle to find the area.
To find the radius, when you have the diameter, divide the diameter by 2, because the diameter forms two radii.
After you have found the radius, plug in the radius into the area equation:
Area = Pi(radius)squared
In other words, you can say the other equation for the area of a circle is:
Area = Pi(1/2Diameter)squared

How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
How do you find diameter of a circle with the area of 58.69?
Diameter is 8.64444
Find the area of a circle with a diameter of 6?
The area of a circle with a diameter of 6 units is: 28.27 square units.
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi

How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How to find the area of a circle?
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.

How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
How do you find the area of an circle when the diameter is 10?
Area of the circle = pi*radius2 = pi*52

How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
