30.46 but round it to the nearest decimal and it will be 30.50

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

Assuming the question refers to a circle with a diameter of 0.9 metres, the circumference is 2.83 m = 2.8 metres to the nearest tenth.

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?"

15.28 inches

The circumference of a 24-inch round (diameter) circle is: 75.4 inches.

The circumference of a 12-inch round circle in pi is: 12pi

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

Circumference = pi * 2 * r C = 3.14 * 2 * 47 = 295.16

The distance around a circle is its circumference

Circumference = Pi * diameterAssuming the "32 inches" mentioned above is the diameter of the circle (and using pi equals 3.14 as a very rough estimate) then the circumference is approximately:3.14 * 32 = 100.48Thus to the nearest option above it is 100 inches.

As for example when constructing a round-about on a road you'll need to know its perimeter which is the circumference of a circle.

circumference is the distance around the circle, so it sounds as though you are stating the circumference in your original question; 66 inches.

For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.

The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
