The area of the circle formula in terms of the diameter is: Area of a Circle = πd2/4. Here 'd' is the diameter of the circle. The diameter of the circle is twice the radius of the circle. d = 2r. Generally from the diameter, we need to first find the radius of the circle and then find the area of the circle. With this formula, we can directly find ...
The circumference of a circle can be used to find the area of that circle. The area of a circle formula in terms of the circumference is given by the formula (Circumference)24π(Circumference)24π. There are usually two simple steps to find the area of a circle from the given circumference of a circle. The circumference of a circle is first used to f...
The area of the circle can be conveniently calculated either from the radius, diameter, or circumference of the circle. The constant used in the calculation of the area of a circle is pi, and it has a fractional numeric value of 22/7 or a decimalvalue of 3.14. Any of the values of pi can be used based on the requirement and the need of the equation...
