Question

use the data of the test scores to make a circle graph.
the pie piece is found by dividing the data by the total and multiplying by 360. be sure to use a title
and to properly label each sector.

1. data: a - 6, b - 8, c - 4

Explanation:

Step1: Calculate total number of data

$$6 + 8+4=18$$

Step2: Calculate angle for A

$$\frac{6}{18}\times360^{\circ}=120^{\circ}$$

Step3: Calculate angle for B

$$\frac{8}{18}\times360^{\circ}=160^{\circ}$$

Step4: Calculate angle for C

$$\frac{4}{18}\times360^{\circ}=80^{\circ}$$

Answer:

The angles for A, B, and C in the circle - graph are \(120^{\circ}\), \(160^{\circ}\), and \(80^{\circ}\) respectively.
