What is the equation for finding the circumference of a circle from the radius?
You multiply the radius by pi.
What is the circumference of radius equals 18 inches?
the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
What is the circumference with a radius of 2.5?
The circumference of a circle with a radius of 2.5 is approximately 15.7075. The equation for the circumference of a circle is Circumference = 2πr where r is the radius. In our case, the radius is 2.5. We can approximate π to be 3.1415. So C = 2 * 3.1415 * 2.5, or C ~= 15.7075
What is the circumference if the area is 379.94 cm square?
The first step is to work out the radius. The formula for area is pi(r2). That equals 379.94, so plug this into the equation and you get a radius of 10.997. The formula for the circumference is pi(2r). Plug the now known radius in and you get 69.097516968554117299881726353374 Therefore the circumference, if the area is 379.94cm2, will be 69.1cm
A circumference is 24 what is the radius?
If the circumference is 24 the radius will be: 3.82
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 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
What is the circumference of a circle with a radius of 15.5cm?
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.
If you Give a circle with a diameter of 4 what is the 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
What is the equation for finding the circumference of a circle from the radius?
You multiply the radius by pi.

2x3.142xr
What is the equation for determining radius of a circle if you have the circumference?
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
How do you measure the circumference of the circle?
The equation for the circumference of a circle is pi times radius squared.
What is the circumference of radius equals 18 inches?
the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
What is the circumference with a radius of 2.5?
The circumference of a circle with a radius of 2.5 is approximately 15.7075. The equation for the circumference of a circle is Circumference = 2πr where r is the radius. In our case, the radius is 2.5. We can approximate π to be 3.1415. So C = 2 * 3.1415 * 2.5, or C ~= 15.7075
