What is the area of a circle with a diameter of 40 inches?
Area = pi * r2r = d/2 = 40/2 = 20Area = 400*pi= 1,256.636 approximate
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
Diameter of circle in inches if the radius is 20 feet.?
40'

What is the area of a circle with a diameter of 80 inches?
A=πr², and r=d/2, so r=40 inches and A = 1600π sq in = 5026.55 sq in
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
If a circle has the diameter of 40 in what is the area?
Area of circle: pi*20^2 = 400*pi square units
If a circles radius is 20 inches what is the circumference?
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
