Circumference = n (pi) x diameter The diameter always equals 2 x radius. So the diameter of this circle is 5. Multiply by pi. 5 x 3.142.. = 15.7 to the nearest decimal place

The circumference is equal to r2*pie or 38.5 inchesAnother answer:Circumference of a circle = 2*pi*radius or pi*diameterCircumference = 7*pi = 21.99114858 or 22.0 inches to one decimal place.

circumference = pi x diameter. So rearranging gives diameter = circumference / pi So diameter = 6/pi = 1.9 inches (1 decimal place)

What is a "9 inch circle"? Is that the circle's diameter ?-- The circumference of a circle is [ (pi) x (diameter)].-- Take that formula.-- Look up the value of (pi), either in your math book or on line.-- Put the value of (pi) in its place in the formula.-- Put the diameter of the circle in its place in the formula.-- Perform the indicated operation (multiplication).-- Bada-bing, you'll have the answer.-- Take a moment to learn the spelling of "circumference".Since you probably didn't understand the big words used above you should just write down 28.26 inches

Estimate: 3*40 = 120 inches Actual: pi*39 = 122.5 inches to one decimal place

Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)

Circumference = n (pi) x diameter The diameter always equals 2 x radius. So the diameter of this circle is 5. Multiply by pi. 5 x 3.142.. = 15.7 to the nearest decimal place

The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.

Assume pi is 3.14 Therefore: Circumference = 3.14 x 15dia = 47.1cm

Circumference of a circle = 2*pi*radius or pi*diameter Circumference = pi*4.2 = 13.19468915 or 13.2 cm to one decimal place

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.

The circumference is equal to r2*pie or 38.5 inchesAnother answer:Circumference of a circle = 2*pi*radius or pi*diameterCircumference = 7*pi = 21.99114858 or 22.0 inches to one decimal place.

11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).

For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.

circumference = pi x diameter. So rearranging gives diameter = circumference / pi So diameter = 6/pi = 1.9 inches (1 decimal place)
