What are the geometry formulas for a circle?
Area = radius2 x 3.1415Circumference = diameter x 3.1415
What is is circumference of a circle is 6.28. What is the area of the circle?
If the circumference of a circle is 6.28 then its area is about 3.138 square units
How do you find the circumference if you a have the area?
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.
What is the area of circle with a circumference of 20?
