The wheel of a bicycle has a radius of 35 centimeters what is the circumference of the wheel?
The wheel's circumference is: 219.9 centimeters.
If a circle has a radius of 8.6 centimeters find its area and circumference in centimeters?
54 cm
What is the radius of a circle with a circumference of 69 centimeters?
Radius = circumference/2pi, in this case 69/2pi or 34.5/3.14, as near 11 cm as makes no difference.
What is the radius of a circle if the circumference is 72?
The equation used to calculate circumference is C = Pi * R^2, where R is the radius and C is the circumference. If one knows the circumference and seeks the radius, then they must divide by pi. Next, they must take the square root. When the circumference is 72, the radius must be approximately 4.8.
If the circumference of a compact disc is 28.26 centimeters What is the radius?
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
What is an equation of the circumference of a circle if the radius is 4 centimeters?
Circumference = 2piR --> 2 x 3.14 x 4 = 25.12 centimeters
What is the circumference of a circle with a radius of 2.8 centimeters?
A circle with a radius of 2.8 centimeters has a circumference of 17.59 centimeters.
What is the equation for finding the radius of a sphere when you know the circumference?
The equation for circumference is C=2(pi)(r) where C is the circumference and r is the radius. You can find the radius by plugging in the circumference into this equation and solving the equation.
What is the circumference of a circle with a 15.5 centimeter radius?
A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
What is the radius of a circle that has a circumference of 44 centimeters?

The wheel of a bicycle has a radius of 35 centimeters what is the circumference of the wheel?
The wheel's circumference is: 219.9 centimeters.
What is the circumference when the radius is r?
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
If radius of a circle is 9 centimeters what would be the circumference?
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
What is the circumference if the radius is 4 centimeters?
50.24
What is the equation for the circumference and radius?
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.
