there are 30 6th graders, 40 seventh graders, and 20 eighth graders marching in a band. How many degrees in a circle graph are needed to represent band members in each grade relative to the entire band

Respuesta :

Answer:

324 degrees

Step-by-step explanation: A circle has 360 degrees. In the question, they are 90 quantities. So that means we need 90% of the circle graph.

So first let divide 90 by 100 which gives us 0.9.

Now let multiply 0.9 times 360 which gives us 324.
