The circumference of a circle can be found from two different starting points, namely from the diameter or the radius. In your case, the formula you can use right away is Circumference = 2 * pi * radius, giving you a circumference of 12*pi, or approx. 37.7 metres. If you prefer working from the diameter, the formula is Circumference = pi * diameter. To calculate the diameter, double the radius to get 12, and then substitute into the formula. You will again get 12*pi as your answer.
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
Area of a circle: pi*radius*radius
12 is the diameter if the radius is 6
A circle with a radius of 6 units has an area of 113.1 square units.
37.7m
The circumference of a circle is 15\piπ m. Find its radius, in meters. The Answer Should Be 7.5
3 meters, 1/2 of the diameter
The circumference of a circle with radius 6 meters is exactly 12 pi meters. If significant figures are important, the calculated length of 37,699111843077518861551720599354 meters must be rounded up to 40 meters
If the diameter is 12 cm the radius is 6 cm.
the radius is one half the diameter,or 6
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
A circle with a radius of 6 mm has a circumference of 37.7 mm
A circle with a radius of 6 feet has a circumference of 37.7 feet.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.
