You can either 1)You can divide out the fraction used for pi then multiply by the diameter or 2)Put the diameter over 1 then multiply across with the fraction used for pi.

What is the circumference of the circle Use 3.14 for?
Not enough information, since you don't specify ANY information about the circle.For example, if you know the diameter, the circumference is pi x diameter; if you know the radius, the circumference is 2 x pi x radius.
Why is the circumference of a circle 360 degrees?
The circumference of a circle is NOT 360 degrees. The circumference is the distance around the curve of the circle. This has a measurement unit of length, not degrees. The angular displacement, in going completely around any point is 360 degrees and that follows from the definition of a degree.
What is the formula to find the circumference of a circle when the diameter is known?
It is NOT a formula but an EQUATION . The answer is C = pi*d This equation has been known for thousands of years. It can also be in the form of C = 2 pi r NB 2r = d Also A = pi r^(2) for the area of a circle.
Why pi in area and angle?
For a square of side a, the area is simple: a2. The perimeter is 4a. How do you deal with a circle, of diameter a? It's obviously less than a2. It turns out to be pi/4 times a2. Or pi times radius squared where pi has been worked out to be 3.1415..... As for angle, for lots of applications it appears a good way of measuring angle by using the length of a piece of circumference of a circle divided by the radius. The units for this is radians. A length of circumference equal to the circle radius gives an angle of 1 in these units when you draw straight lines from the ends of this bit of circumference to the centre. So the whole way around the circle (360o) then is 2.pi.r divided br r, radians, which is just 2 pi radians.
What is the surface area of a cylinder if the circumference equals 37.69911184307752?
There is no point in giving the circumference to 14 decimal places but no information about the height. You would have been far better giving the circumference to 2 decimal places and the height. As it is, the question cannot be answered.
What is the circumference of the given circle?
We've not been given a circle.
How do you solve the questions on Circular Measure?
That depends on the questions which have not been given but in general circular measurements are:- Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2
What is the circumference of a circle that has a diameter of inch Express your answer as a decimal?
That depends on its diamter which has not been given but the circumference of a circle is diameter times pi
Find the circumference of a circle with radius of inches (use 3.14for Pi)?
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
Who made circumference of a circle?
People have been drawing circles for a very long time.
What is the measure of an arc that is intercepted by an inscribed angle of 31 degrees?
That will depend on the circumference of the circle which has not been given
What is the circumference of a circle with 3.14 used instead of pi?
That would depend on its diameter or radius which have not been given
What is the circumference of the circle Use 3.14 for?
Not enough information, since you don't specify ANY information about the circle.For example, if you know the diameter, the circumference is pi x diameter; if you know the radius, the circumference is 2 x pi x radius.
What iS the radius of a circle with circumference?
A circle is a shape with all points the same distance from the center. It is named by the center. The circle to the left is called circle A since the center is at point A. If you measure the distance around a circle and divide it by the distance across the circle through the center, you will always come close to a particular value, depending upon the accuracy of your measurement. This value is approximately 3.14159265358979323846... We use the Greek letter (pronounced Pi) to represent this value. The number goes on forever. However, using computers, has been calculated to over 1 trillion digits past the decimal point.The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. is the ratio of the circumference of a circle to the diameter. Thus, for any circle, if you divide the circumference by the diameter, you get a value close to . This relationship is expressed in the following formula:where is circumference and is diameter. You can test this formula at home with a round dinner plate. If you measure the circumference and the diameter of the plate and then divide by , your quotient should come close to . Another way to write this formula is: where · means multiply. This second formula is commonly used in problems where the diameter is given and the circumference is not known (see the examples below).The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius. This relationship is expressed in the following formula: , where is the diameter and is the radius.
Did pi ever solve a problem?
The constant "pi" 0,314159...... is used in every branch of science, from calculating material quantity for domes in construction to calculating absorption properties of new substances in chemistry. To calculate the circumference of a circle = c = 2(pi)r The area of a circle a = (pi)r² you can also use the formula (pi)d to find the circumference Although pi has solved countless problems, no problem has ever been solved with whatever pi equals EXACTLY. Therefore, when using pi to solve a problem, the majority of mathematicians and scientists round pi down to 3.14
What is the circumference of a circle if it's area is 120 inches?
This question has already been answered in detail and the answer is 38.83251825 or 39 inches to the nearest foot.
Why is the circumference of a circle 360 degrees?
The circumference of a circle is NOT 360 degrees. The circumference is the distance around the curve of the circle. This has a measurement unit of length, not degrees. The angular displacement, in going completely around any point is 360 degrees and that follows from the definition of a degree.
