How do you find the circumference of a circle using pi on a calculator?
Most scientific calculators have a button for pi. So to find the circumference of a circle multiply pi by the diameter. If there is no pi button you can approximate pi as 3.14.
What is the circumference of a loonie?
A circumference is 4
What is the circumference of a circle whose diameter is 200 m?
The diameter times pi. Pi is approximately 3.1416. Scientific calculators also have a button to quickly access the value pi.
What definition of circumference?
The circumference is the distance around a closed curve. Circumference is a special perimeter.
What is the relationship between diamter and circumference?
circumference = pi*diameter or pi = circumference/diameter
What formula do you use to find the diameter of the circumference?
the circumference of the circle divided by pi (button or 3.14) - Maths

What is the circumference of the home button on an iPhone?
Let D be the Diameter and C be the circumference.C=D X π (pi, about 3.14)C=1cm X 3.14C=3.14cmThe circumference of the home button on an iPhone is 3.14cm.
In order for a button to fit through its buttonhole the hole needs to be the size of the button's diameter. What size buttonhole is needed for a button with a circumference of 9.42 centimeters?
A.3 centimeters
What size buttonhole is needed for a button with a circumference of 7.38 centimeters Use the value of 3.14 to represent pi?
for a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. what size buttonhole is needed for a button with a circumference of 9.42 centimeters?
What size button hole is needed for a button with a circumference of 7.38 centimeters use the value of 3.14 to represent pi?
A buttonhole will need to be as wide as the widest part of the button, if the button is to be able to pass through it. A button is a circle shape; the widest part of a circle is its diameter. The formula to find the circumference of a circle is Pi multiplied by the diameter of a circle. We already know the circumference of the button, and we know the value of Pi, so we can rearrange the above formula: 3.14 x diameter = 7.38 ---> 7.38 / 3.14 = diameter So, the diameter of the button is 2.35 cm. The buttonhole will therefore need to be this size. Actually, probably a tiny bit bigger unless you want it to be extremely tight!
If the radius is 4cm what is he circumference?
Circumference of a circle is C=2pir C=2pi(4) C=8pi C=25.12 cm Where pi is the ratio of the circumference to the diameter of any circle, approximately 3.14. There is usually a button for pi on scientific/graphing calculators.
What size buttonhole is needed for a button with a circumference of 7.38 centimeters (Use the value of 3.14 to represent pi.)?
3.69
How do you find circumference if you have radius?
First of all, let's define circumference. Circumference is the diameter of a circle times pi (3.14) So it would take 3.14 diameters to go around the circumference of a circle. A radius is from the center of a circle to the outside. It is half the length of the diameter. So, take the radius and double it. That will give you the diameter. Take the diameter and multiply it by pi. Pi is the button on your scientific calculator that looks like Stonehenge. If you do not have a pi button, 3.14 will give you a rough estimate.
How do you work out the circumfrance of a circle using the pi button?
-- enter the diameter of the circle-- hit the big ' X ' for "times"-- enter (pi) with the pi button-- touch " = " ('equals')The circumference is displayed.
Is Clw the formula for the circumference of an circle?
To find the circumference of a circle, multiply the diameter by Pi. Pi is written as 3.14 or just use the Pi button on a calculator. You could also write something to the effect of 3pi.
An introduction of pi?
Pi is the ratio of the circumference of a circle to its diameter; it can be calculated as circumference divided by diameter, or circumference/diameter. It is an irrational number which starts 3.14159265358979323846264338327050..., but it is usually approximated to 3.14 or 22/7, though using the [π] button on a calculator makes it easier to enter a fairly accurate value.
