A circle with a radius of 2.8 centimeters has a circumference of 17.59 centimeters.
A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
A circle with a radius of 4.5 centimetres has a circumference of 28.27 centimetres.
A circle has the radius of 27.7 cm what is the approximate circumference of the circle? The circumference is approx. 174 centimeters.
The radius is 7cm
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
the equation for the circumference is Pi * double the radius which is 3.1416 * 15.5 * 2 The circumference of a circle with a radius of 15.5cm is 97.3cm.
The equation for circumference is 2(3.14)(r) or 3.14(d) where r=radius and d=diameter. The radius of a circle is half of the circumference, or the distance across the interior of a circle.
The radius is: 4.802 cm
11.00
The equation for the circumference of a circle is pi times radius squared.
