Steps involving to solve circle graphs:
For example take this problem, in an office there are 230 staffs in first floor, 320 staffs in second floor and 150 staffs in third floor. Draw circle graphs to mention the numbers of staffs in each floor.
Solution:
Step 1: At first take all the given data and add; it is nothing but the Total number.
Total number of staffs in an office = 320 + 150 + 230 = 700
Step 2: After that convert each and every value of the data's into angles by dividing with total number and multiply with 360.
Percentage of staffs in first floor as angles = 230/700*360 = 118.5
Percentage of staffs in second floor as Angle = 320/700*360 = 164.5
Percentage of staffs in third floor as Angle = 150/700*360 = 77
Step 3: Then draw the circle graph by using the solved value in angles.
Then the circle graph is get as,

How do you solve fractions?
You cannot solve fractions. There may be sums or products containing fractions or equations that can be solved. But fractions themselves cannot.
How can you use turnaround facts to help you find sums?
Turnaround facts help you solve sums by encouraging you to start with the greater number first and add the lesser. ie. 5 + 1 = 6 is easier to solve than 1 + 5 = 6
How do you solve a magic box?
To solve a Magic Box you must plug in numbers that make the sums of the columns, rows, and diagonals equal the same amount.
How do you solve the circle?
The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

How do you do circle sums for the sum of 20?
There is no "sum of 20". To have a sum, you have to have at least 2 things to add together.
How do you solve negative sums?
if you get a -4 x -3 you would get 12 because a negative and a negative will give you a positive.
How do you solve segment lengths in a circle?
It depends on what information you have.

How do you solve circle area of 24centemeter?
You cannot SOLVE a circle. You can find the radius of a circle, or its diameter, or circumference or area. Or you can find the equation of a circle in the Cartesian system or in polar coordinates. Or find other characteristics of the circle. In any case, a circle cannot have an area of 24 centemeter. Apart from the fact that there is no such word - try centimetre (or centimeter). A centimetre is a measure of length, not area.
How do you you solve for the area of a circle?
You use the information you're given, along with the facts and formulas you know about the geometry of a circle.
