Hi, I'm confused on how to find degrees for a percent. I think I have to first multiply the percent by 360°.
c.) What is 18% [blue ski wax] in degrees?
Oh, actually I think I know now:
First convert the 18% to a decimal, which is .18 and THEN multiply it by 360°.
Is this correct?
Yes
You have the method right, but what do degrees have to do with it?
Thanks. I have to learn the degrees for the percent to be able to make a circle graph with a protractor.
To find the degrees for a percent, you need to know that 100% is equal to 360 degrees in a circle. Therefore, you can use the proportion:
[Percent] / 100% = [Degrees] / 360°
To find the degrees for 18%, you can substitute the values into the proportion:
18% / 100% = [Degrees] / 360°
Now, you can solve for [Degrees] by cross-multiplying:
18% * 360° = [Degrees] * 100%
To evaluate this, you need to recognize that the percentage symbol "%" can be treated as a decimal value by dividing it by 100. So, 18% is equal to 18/100 or 0.18.
Let's substitute this value into the equation:
0.18 * 360° = [Degrees] * 100%
Multiplying 0.18 by 360° gives us:
64.8° = [Degrees] * 100%
Now, we can solve for [Degrees] by dividing both sides of the equation by 100:
64.8° / 100% = [Degrees]
Simplifying this expression, we get:
0.648° = [Degrees]
Therefore, 18% is equal to 0.648 degrees.
