To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
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.
Area of a circle = pi times radius squaredDiameter of a circle = 2 times radius
Diameter is 8.64444
The area of a circle with a diameter of 6 units is: 28.27 square units.
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.
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
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
Area = 1/4 of (pi) x (diameter)2
Area of a circle = pi*radius2 Radius = diameter/2
Area of the circle = pi*radius2 = pi*52
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)
Area = Pi(d/2)2 where d = diameter
pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
Area of a circle = (pi) (R2)R = radius of the circle = 1/2 of its diameter
The area of a circle is Pi(3.1416)*radius2 if you do not have the radius, it is just half of the diameter.
Area of a circle without pi = (circumference/diameter)*radius2
I assume that you are referring to the area of a circle. You divide the diameter in half to find the radius and then you put it into the formula.
A circle with a diameter of 11 inches has an area of 95.03 square inches.
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
The area of a circle is pi(radius)2 Radius is half the diameter. Simply divide the diameter in half and enter it into the equation 3.14(diameter/2)2
The diameter of a circle with an area of 37.68 is 6.92
Area = 33.2 cm2
