The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
the diameter is the length across the circle, the area is pie r squared r is radius, which is half of the diameter
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.

The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
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
No. The area of a circle is 3.142 x radius x radius (radius is half the diameter).
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
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)
The area of a circle is Pi(3.1416)*radius2 if you do not have the radius, it is just half of the diameter.
Hold it right there. That's not possible. Something's gotta give.The area of a circle = pi R2 = pi (half the diameter)2If the circle has a diameter of 16, then its area is 201.1(rounded).If it has an area of 64, then its diameter is 9.03(rounded).If it has a diameter of 16 and an area of 64, then it's not a circle.
half of the radius the radius is half of the diameter the diameter is the with of the circle. This also can be called a quadrent circle.
The radius is half of the diameter of a circle.
