By using the formula: area of circle = pi*radius2

The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.

For a circle, area = Pi x radius2

It depends on the shape you need the area of, the most common one is for a circle. That is Area=Diameter x Pi

The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14

Area of a circle = pi*radius squared

Use the formula for the area of a circle: area = pi x radius squared The radius is half the diameter.

To find the area of a circle using the circumference, you need to use the formula Area=Circumference squared divided by four times pi. For this type of equation, pi would be equal to 3.14.

The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2

The area of Circle S can be found by using the area formula for circles. The area of a circle is pi times the radius squared. So, the area of Circle S with a 1 inch radius is Pi inches squared.

area of a circle = pi*r2

The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.

The area of a plate will likely be found using the formula for the area of a circle. This is the product of pi*(r^2).

You can find the circumference of a circle if you know its area by using the formulas for area and circumference. First, use the formula for area: A = pi r2. Replace A with the number for the area. Solve the formula for r, the radius of the circle, dividing A by pi and taking the square root of the answer. Once you have the number for r, the radius of the circle, plug that value in place of r in the formula for the circumference: C = 2 pi r. Then you can calculate the circumference of the circle by multiplying pi times twice the radius.
