Circumference is calculated from radius as C = pi x r x 2 To find the circumference of a circle with a diameter of 8 meters, simply multiply the radius (8) by 2, then multiply the product by pi (approximately 3.14159). This should give you around 50.3 meters.

radius = 5 m so circumference = 2*pi*r = 31.4159 m (to 4 dp)

32 meters squared, if the circumference is 20 meters you divide that by pi to get the diameter. Then divide by two to get the radius. Multiply the radius by itself and then by pi to get the area and round to 32.

Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth

Radius = 130.51 mm approx.

circumference = 2*pi*radius. If we round pi to 3.14, the radius is 31.4/(2*3.14)=5.

A circle with a radius of 4 units has a circumference of 25.13 units.

Circumference of a circle = 2*pi*radius or diameter*pi

Circumference of a circle = 2*pi*radius or pi*diameter

Circumference of any circle = 2*pi*radius or diameter*pi

If 34 inches is the radius or diameter of the circle, (or circumference?), it needs to be stated in the question! What is meant by "round circle?"

3 meters.
