Question

the population of students in a school is 810. if this is represeted on a pie chart, calculate the sectorial angle for a class of 72 student​

Answer 1

Answer:

32°

Step-by-step explanation:

The population of students in a school is 810.

We want to find the sectoral angle that corresponds to 72, if we should represent this on the pie chart.

This is given by number of students in class over total times 360.

$= \frac{72}{810} \times 360 = 32 \degree$

The required central angle is 32°
