The circumference od a circle is less then three time the length of the diameter?
No. The formula for circumference of a circle is pi x diameter. As pi is 3.14... then the circumference will be at least 3.14 times the diameter.
How do you estimate the circumference of a circle if you know the diameter?
To estimate the circumference, multiply the diameter by 3. If you have a calculator or are decent at multiplication and have the time, multiply it by 3.14. If you can, multiply it by pi.
What do people use pi for?
Since pi is the ratio of the circumference of any circle to its diameter, it comes up any time a radius or diameter is used to calculate most other characteristics of a circle or a sphere, such as circumference, area, surface area or volume, or whenever any of those characteristics are used to calculate a radius or diameter.
If a compass spins twice around is the circumference doubled?
Yes! If It spins one time, then that is the circumference. Therefore if you spin it a second time, that doubles it!
What is the diameter radius circumference and are of a circle with a diameter of 80 ft?
Diameter: Well, you said it yourself, 80 feet. Diameter is the distance across the widest part of a circle. Radius: The radius of a circle is half of the diameter, so in this case, it would be 40 feet. The radius is the distance from the center of the circle to the outside. Circumference: The formula for circumference is Pi (3.14 or 22/7) times the diameter. In this case, it would turn out to be 251.2 feet. Area: The formula for the area of a circle is Pi time the radius squared. So, you square the radius and multiply that by Pi (3.14). In this case, it would be 15775.36 feet squared. I hope I made sense. :)
How do you create a circumference formula?
the circumference of a circle is pi time the diameter
The circumference od a circle is less then three time the length of the diameter?
No. The formula for circumference of a circle is pi x diameter. As pi is 3.14... then the circumference will be at least 3.14 times the diameter.
Is a circumference approximately three time the diameter?
Yes because circumference = diameter*pi and the value of pi is just over 3
What is pi to the nearest hundredth place?
3.14
How many diameters equal a circumference?
circumference = 2 x pi x radius which is the same as pi x diameter so the answer is pi.
If diameter is 26 inches what is the circumference?
The circumference of a circle is obtained by multiplying the diameter time pi (3.1416...). 26 inches times pi = 81.68 inches.
How do you estimate the circumference of a circle if you know the diameter?
To estimate the circumference, multiply the diameter by 3. If you have a calculator or are decent at multiplication and have the time, multiply it by 3.14. If you can, multiply it by pi.
What is the circumference of a 36 inch circle?
Circumference of any circle = 2*pi*radius or diameter*pi
How many thousandths of an inch are in 22 degrees at a diameter of 3.473?
First find the circumference, then multiply by 22/360 to get the arclength. The circumference is pi time the diameter (or 2pi times the radius). Pi times 3.473 is 10.9107512. Multiplying that by 22, and dividing by 360 is .667 after rounding. The answer is 667 thousandths.
