What does 'pi' mean in math terms?
In math terms, pi, means 3.14, which is a everlasting decimal, that is just rounded to make your math easier. So pi, means 3.14 in math terms.
Is a smaller circle or larger circle easier?
depending on the circles equation..a larger circle is easier
What is the curcumference of a circle with a 16 meter radius?
Well first you find on your calculator you need to find pi which looks something like this π. Now to find the curcumference of any circle the formula is pi multiplied by the diameter. The radius is 16 metres, and the diameter of any circle in life is two multiplied by the radius. So you do π times by 32 which equals 100.53(I rounded it off to the nearest 2 decimal places). or even easier 3.14 x radius 2 l l l PI times raduis 2 and now for area 2 times 3.14 times raduis
What is the formula to calculate the area of a circle?
*=multiplication symbol /=division symbol r*(r*ㅠ)=r2 ......... radius*(radius*pi)=radius2 ........... radius times the radius times pi equals radius squared HINT HINT HINT an easier way to put this is .......... d*ㅠ/2=n ............. diameter*ㅠ/2=answer .......... diameter times pi divided by two equals the answer
Why is a circle like a ball?
The ball is circle in shape because it is spherical in form and it is easier to control or to handle. Like the ring in the basketball,it is seems like a shape in a ball(spherical) so that it is easy to shoot the ball into the ring.
Why would you use a formula to determine the circumference of a circle rather than measuring the circumference?
Because the circumference of a circle isn't a straight line its hard to measure, even if you have a flexi-ruler, your never going to be able to line it up to get an exact measurement. Therefore its much easier to measure the diameter and use the formula
What is mean by pi in mathematics?
If you mean pi as in 3.14159... I can answer. Pi is a relationship that compares the circumference of a circle to the diameter of that same circle by division. In any circle, if you divide the length of the circumference of that circle by the length of its diameter you will get 3.14159... or pi. This can be very helpful to know because it is much easier to measure the diameter of a circle than to measure the distance around the circle (circumference). If you multiply the diameter by 3.14159... you will find the circumference. If C = circumference; D = diameter; pi = 3.14159 theses are some useful formulas: C = D X 3.14159 or D = C / 3.14159 or 3.14159 = C / D
What is harder.Measuring the circumference.Why?
To measure circumference the measuring instrument must follow the curved path exactly which will be difficult without special instruments. It is easier to calculate a circumference by measuring a straight line diameter and then multiply that dimension with Pi (3.141593....).
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.
What is the diameter of a circle if the circumference is 18 feet 8 inches?
the formula to start off with is the circumference is pi x diameter therefore re-arranging the formula the diameter is the circumference divided by pi diameter = circumference / pi = 18ft 8in / 3.1415 = 5ft and 11 inches to the nearest inch (to be more precice to diameter is 5ft 11.3 inches--- note it is more difficult to work in feet and inches and easier to work in metres and centimetres)
How do you measure the circumference of a cirlcle?
You need to measure it with something flexible, like a string.If you know for sure it is a circle, it would be easier to measure the diameter, then multiply by pi.
Would you use a measuring tape or a meter-rule to measure the circumference of a baby's head and why?
I would use a measuring tape because it is easier to wrap it around a baby's head.
What is the perimeter of a circle?
the radius2 x pi x r where pi = 3.1416To find the perimeter you do pi (3.1415) times the diameter.Or you can figure by the radius (P=2 π r; i.e. Perimeter = 2 x 3.1415 x radius)The perimeter of a circle is its circumference. We use these formulas to find the circumference of a circle; C=d times pi or C=2 times the radius times pi (3.14).To make it easier to explain:Area: Pi (3.14) X Radius Squared (r 2) from the center out of the circlePerimeter: Pi (3.14) X Diameter (d) from one side of the circle to the otherThe perimeter of a circle is called Circumfrence.Here is the formula for Circumfrence:C= pi x d (pi times diameter)C= 3.14 x ______ (fill in the blank with the diameter of the circle)C= (your answer)NOTE: Pi is equal to 3.14 so when you are using pi to multiply, replace it with 3.14When the diameter is not given in a circle, double the radius to find the length of the diameter.The perimeter of a circle is its circumferenceThe perimeter of a circle is its circumference
Why mathematics call 3.14 pi?
Well, 3.14 isn't really accurate pi. pi is the value when circumference of the circle is divided by it's radius. It makes easier to estimate the length of circumference of the circle. Pi = 3.141592..............(infinite)
What does 'pi' mean in math terms?
In math terms, pi, means 3.14, which is a everlasting decimal, that is just rounded to make your math easier. So pi, means 3.14 in math terms.
What is the formula for the perimeter of a circle?
2 x pi x r where pi = 3.1416orpi x diameter.To find the perimeter you do pi (3.1415) times the diameter.Or you can figure by the radius (P=2 π r; i.e. Perimeter = 2 x 3.1415 x radius)The perimeter of a circle is its circumference. We use these formulas to find the circumference of a circle;C=d times pi orC=2 times the radius times pi (3.14).To make it easier to explain:Area: Pi (3.14) X Radius Squared (r 2) from the center out of the circlePerimeter: Pi (3.14) X Diameter (d) from one side of the circle to the otherThe perimeter of a circle is called Circumference.Here is the formula for Circumference:C= pi x d (pi times diameter)C= 3.14 x ______ (fill in the blank with the diameter of the circle)C= (your answer)NOTE: Pi is approximately 3.14 so when you are using pi to multiply, replace it with 3.14When the diameter is not given in a circle, double the radius to find the length of the diameter.
How many feet are in a diameter of 12 feet and a circumference of 38 feet?
It is easier to use the diameter. The radius is half of the diameter, 6. Area is pi x r x r 3.14 x 6 x 6=
