What fraction of a pie graph is 30 degrees?
Since a complete circle is 360 degrees, a 30-degree part of a circle is 30/360, or 1/12, of the pie.
What fraction of a pie graph is 60 degrees?
one sixth
How would you calculate the angle to show twenty percent on a circle graph?
Multiply the percentage by 3.6
How do you use the Pythagoras theorem in circle?
In a circle that has a radius of one you use Pythagorean theorem to derive the sine, cosine and tangent formulas. Draw a circle around the origin on graph paper. The sine is the line segment from the point where the side of the angle intersects down to the x-axis. etc.
How find sin30?
On a calculator type in 'Sin' , followed by '30' follwed by '=' . The answer is '0,5'. Sin(30) = 0.5 All the trig. values are based on a triangle integrated into a circle. Practically, On a piece of graph paper, draw a circle centred on the origin (0,0). Call the radius of that circle '1'. Now draw a radius 30 degrees from the x-axis. Then drop a line from point on the circle were the radius meets( intersects) the circle. to the x-axis, to meet the x-axis at 90 degrees. This 'dropped' line is the 'opposite' to the angle 30 degrees. Measure the length of this 'dropped'; line. You will find it to be exactly half (0.5 = 1/2) the length of the radius. Similarly, if the radial angle is 45 degrees a corresponding sine value is 0.707106781... = sqrt(2)/2 = 1/sqrt(2). All other 'Sine' values can be found in a similar manner. However, to save time on drawing circles and triangles, the trig. values are integrated into modern calculators or formerly into Castle's Four Figure Tables.
How do you you turn degrees into percents on a circle graph?
Divide the amount of degrees by 3.6 to change it to percent.
Scentific definition of a circle graph?

What is 75.6 in degrees on a circle graph?
In a circle graph, also known as a pie chart, the total degrees in a circle is 360. To calculate the degrees for 75.6 in a circle graph, you would use the formula: (75.6 / 100) * 360 = 271.44 degrees. Therefore, 75.6 in degrees on a circle graph would be approximately 271.44 degrees.
What is a circle graph is genneral?
a circle graph can hold a certain fraction, or percents, or numbers. it has to do with math and stuff it can not show change over time. also referred to as a pie graph
What percent of a circle graph measures 18 degrees?
18 degrees is 5% on a circle graph.
What is the degrees of a circle graph?
360 degrees.
How do you convert degrees from a circle graph into numbers?
360 degrees = Total number, T. So a sector of x degrees is equivalent to x*T/360 units.
When do you use a circle graph?
You use a circle graph when you need to find percentage and/or degrees.
If a section of a circle graph measures 180 degrees what percent of a circle graph is this section?
50
What is difference between a bar graph circle graph and line graph and when would you use them?
I'm in sixth grade and I use circle graphs in social studies and bar and line graphs in science
