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.

What is the circumference of 40 inches?

Well this depends on If the radius is 40 inches or If 40 inches is the entire diameter. Circumference is determined using the formula Pi x Radius² Assuming 40 is only a radius it would be 3.14 x 40² or 3.14 x 1600 = 5024 inches If 40 inches is the entire diameter then its simply Pi x Diameter since the entire diameter is the radius squared. 3.14 x 40 = 125.6 inches.

How can i find the circumference of circle with radius of 40 inches?

The formula to figure out the circumference of a circle is C=2(pi)r. So with a circle that has a radius of 40 inches, you can set up the formula like: C=2(pi)40. To figure this out on a calculator, multiply 2 with pi and then multiply that answer with 40. If you do not have a pi symbol on your calculator you can multiply 2 with 3.14159 then multiply that answer with 40.
