Help! Degrees and Percents for numbers!

Question

age: 20-29 members: 4
age: 30-39 members: 5
age: 40-49 members: 6
age: 50-59 members: 8
age: 60-69 members: 2

What is the percent and degreee for each.
then determine degree of each angle that would be used to draw each section of the pie graph by multiplying the percent, as a decimal, times 360. List the size of the angle, to the nearest whole degree

Answer 1

Hello, Jane!

I'm not positive I fully understand the question, but here's what I'm thinking. Let me know if I've misunderstood.

First, add the numbers of each groups' members to find the total number of members. 4+5+6+8+2=25.

To find the percentage of each member group to the whole, simply divide each groups' total by 25. For example, for age 20-29 members, there are 4 people, so divide 4 by 25. 4/25=.16, or 16%.

You should now have .16, .20, .24, .32, and .08 for each group, respectively.

Finally, do as instructed, and multiply your percents (as decimals) by 360. For example, the first group comprises 16% of the total members, and in degrees, it would be (.16)(360)=57.6. Remember you're asked to round to the nearest whole degree, so 57.6 would round to 58 degrees.  This is your angle size for group 1.  I'll let you figure out the rest.

Hope this helps!
