SOURCE: getting the excel formula

Suppose the value for $ is stored in cell A3. Your formula would look like this: =(A3+A3*0.25)*1.5

The equals sign at the beginning of the formula is necessary. And if you want the result to be formatted as currency, you can do so by right-clicking the cell or column, format cell, number tab, choose currency.

SOURCE: formula for a percentage of something

the formula would be as follows:

X + Y%(X) = Z or 176.37 + .128(176.37)=198.95

If you were going to do this in MS Excelit would be:

assume 176.37 is in A! and the .128 is in A2 and the total will be in A3

A1 + A2(A1) = A3

Remember to multiply by percent, first divide the percent by 100

5% would be .05

Hope this helps

What is the area of a circle if the circumference is 2 pi inches

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 the relevant formula.

15" circle what is outside measurement

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)

Formula for circumference

Circumference of a Circle: 2 x pi x radius - OR - pi x diameter,

or if you need some sphere calculations?

Sphere Surface Area: 4 X pi X radius squared OR
pi X diameter squared Sphere Volume: 4/3 X pi X radius cubed OR
( pi X diameter cubed ) / 6
By the way.......... "pi" = 3.1415926536

What is the circumference of a circle with a radius of 10 2/7 feet. Use 3.14 as pi.

Using the formula: C = Pi * Diameter ..... where Diameter = 2* radius

Your circumference is Pi x 2 x 10 2/7 ft

How to solve the circumference by using fomulae p=2

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.

Circle equation

If you know the center, measure the distance between the center and one point on the circumference. Measure with the opening of a compass and report on a ruler, or use a ruler.
Take the measure of the radius and multiply by 2. Any other indirect way of getting the radius does not constitute a measure but a calculation.
The diameter of a circle enters in two formulas.
Length of Circumference: C=Pi*D (D diameter) ====>D=C/Pi
Area of the disk A=Pi *D^2/4 =====>D=SQRT(4*A/Pi), SQRT is the square root operation.

If you know about area formulas of class 8 and 9,please solve my question?there is a the between of the circle,there is a rectangle of dimension 4cm and 3cm.if the rectangle will cut out what...

The diameter of the circle is the diagonal of the rectangle use Pythagoras this rectangle is a made from two 3,4,5 triangles, so the diameter is 5cm, the radius will be 2.5cm don't forget the BODMAS ordering rule (Brackets of Division Multiplication Addition and Subtraction) Also rounding to 2 decimal places. This solution is based on all four corners of the rectangle touching the circumference of the circle.

Area of a circle is P (22/7) i x Radius (squared ^2) ====> 22/7 x 2.5cm ^ 2 ====> 22/7 x 6.25cm

TOTAL AREA of CIRCLE = 19.64 cm^2

Area of the rectangle is length x width ====> 4 cm x 3 cm


The remaining portion is the circle area minus the rectangle 19.64-12 = 7.64 cm^2

Example of program in c++ and there code

Hello my friend, I am Jonas I work as a programmer in some various programming languages. Here try this code:
This program is design to output the Diameter, circumference, and area given a radius of a circle. #include <iostream.h> int main() { int radius, diameter, circumference, area, pi; cout << " Enter the radius of a circle\n"; cin >> radius; pi = 3.14159; diameter = 2 * radius; circumference = 2 * pi * radius; area = pi * (radius)^2; cout << "Diameter formula executing.....(2 x r)\n"; cout << "Diameter is " << diameter << endl; cout << "circumference formula executing.....(2 x pi x r)\n"; cout << "circumference is " << circumference << endl; cout << "area formula executing......(pi x [r x r])\n"; cout << "area is " << area << endl; return 0; }

What is the area of a semi circle the diameter is 2.500mm the radious is .425mm the circumfrence is 3000mm

You cannot have a semicircle that has a diameter of 2.500 mm and a radius of .425mm and a circumference of 3000mm

Circumference is equal to pi times the diameter. pi is = 3.14

The radius of a circle is always 1/2 the diameter

Area of a circle is pi time the radius squared
