Question about Gateway FPD1975W 19" LCD Monitor

area formula is PI x r squared

that is 3.1417 times the radius of the circle squared

example is:- 3.1417 times 3 inches squared =3.1417 times 3x3=3.1417x9=28.279 square inches if you want to work back from a circumference measurement, the formula for circumference is 2 x PI x radius or PI x diameter

if you have a circumference of 12 inches then the dia is calculated 12 inches = dia x PI to get the diameter , divide the 12 inches by PI and that will be the diameter so that is 12 divided by 3.1417 =3.819 inches

now you can go from the first formula the radius is the diameter divided by 2 so the radius will be 3.819 divided by 2 = 1.909 inches

so applying the area formula it becomes 3.1417 times 1.909 times 1.909 =11.458 square inches

to find your answer simply substitute the dimensions in place of the example figures.in the relevant formula.

If you would like to know the circumference of a 15" diameter circle this is the formula:

circumference = radius x 2 x pi

circumference = diameter x pi

in our case:

circumference = 15" x 3,14

circumference = 47 ,1" (that's 119,634 cm)

circumference = radius x 2 x pi

circumference = diameter x pi

in our case:

circumference = 15" x 3,14

circumference = 47 ,1" (that's 119,634 cm)

The formula is simply this: **C = (pi)d**. In this equation, "c" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi, which is an approximation of 3.14.

The circumference (C) of a circle and its diameter (D) are related by

C=PI*D (Pi is the famous constant)

**D=C/Pi**

C=PI*D (Pi is the famous constant)

To get a circle with a perimeter of 18 inches, you want a diameter of about 5.73 inches (just under 5 3/4 inches) or a radius of 2.86 inches (call it 2 7/8 inches). Get a compass, set its legs 2 and 7/8 inches apart, put one end at the center, and turn.

30" diameter? Radius is 15" (half of diameter).

30" circumference (distance around) is a little more complicated...

The number is the ratio of the circumference of a circle to the diameter. The value of is approximately 3.14159265358979323846...The diameter of a circle is twice the radius. Given the diameter or radius of a circle, we can find the circumference. We can also find the diameter (and radius) of a circle given the circumference. The formulas for diameter and circumference of a circle are listed below. We round to 3.14 in order to simplify our calculations.
