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 do you find the area of diameter of a circle?
You misunderstand. 'The area of the diameter'. The diameter is a STRAIGHT LINE, it is NOT an area. The question should read ' How do you find the area of a circle, knowing only the diameter?' To answer the question Remember the equation ;- A = pi*r^2 Where 'A' is the area 'pi' ~ 3.14 (A constant) 'r' is the radius. Now the radius is one half the diameter ; (r = d/2) or (d = 2r) We can algebraically substitute A = pi *(d/2)^2 So as an example , is the diameter is 20 Then A = 3.14 ( 20/2)^2 (Remember ; do what's inside the brackets first) A = 3.14 * 10^2 A = 3.14 * 100 A = 314.00

400 pi
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
How do you calculate the square footage of a 20' diameter circle?
The area of a circle is computed by the formula A = pi * r2 (r is the radius of the circle)For a 20 foot circle, the radius is 10 feet and the area is 314.16 square feet.
