What is area of circle of 20 radius?
1,256.6 units2
If area of circle is 100pi what is the diameter?
Oh, isn't that a happy little question! If the area of a circle is 100π, we can use the formula for the area of a circle, which is πr^2. So, 100π = πr^2. By solving for the radius (r), we find that the radius is 10 units. And since the diameter is just twice the radius, the diameter would be 20 units.
What is the radius of a circle whose circumference is 40 pi?
The radius of a circle whose circumference is 40pi is 20 units.
If the radius of a circle is 20 what is the diameter?
The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.

How many square inches in a 40 inch diameter circle?
Area of a circle = πr² (remember that r or radius is exactly half of the diameter) Radius therefore = 40/2 = 20 inches Thus the Area = 3.14159 × 20 squared = 1256.636 square inches
