### 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 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.

### 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.

### 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 equation for finding the circumference of a circle from the radius?

You multiply the radius by pi.

2x3.142xr

### What is the circumference when the radius is r?

To find the circumference of a circle, use the equation: Circumference = 2*&pi;*radius so when the radius is r, the circumference is 2&pi;r

### What is the circumference of a circle if the radius is 4.83cm?

The circumference of a circle is given by the equation C=2*pi*r (r being the circle's radius). So, the circumference you're looking for is 30.35 cm.

### What is the standard equation of the circle?

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

### What is the circumference of a circle if the radius is 5meters?

To find the circumference of a circle the equation would be pi multiplied by diameter, or radius squared. the answer would be 31.415 units squared.

### 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 = 2&pi;r where r is the radius. In our case, the radius is 2.5. We can approximate &pi; to be 3.1415. So C = 2 * 3.1415 * 2.5, or C ~= 15.7075

### How do you find the circumference if you have the area of a circle?

Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
