Do you mean of a circle?
D = 2r
A = (pi)r(squared) {Sorry, I don't have the actual symbols on my phone}
You need to give the shape.
well it is benificial to know the area of a shape because to find the circumference, radius, and diameter u must know the area of the shape well it is benificial to know the area of a shape because to find the circumference, radius, and diameter u must know the area of the shape
It would be benifical to know the area of a shape because without it you cant find the diameter radius or circumference
To calculate the area of a pipe (which is a cylindrical shape), you can use the formula for the cross-sectional area of a cylinder, ( A = \pi r^2 ), where ( r ) is the radius of the pipe. If you have the diameter, you can find the radius by dividing the diameter by 2. For a pipe with a specific outer diameter and thickness, you would use the inner radius to find the area of the flow section.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
A circular shape with an area of 65 square feet has a diameter of 9.1 ft approx.
Diameter is 8.64444
It depends on the shape of the area. If it is a circle with an area of 4,300 acres, the diameter of the circle would be 15,440 feet.
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
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
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.
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
