Question

A student recorded the favorite dipping sauces of the 70 people in his class. He wants to plot these data in a circle graph:

What angle should the wedge for barbecue have?

A.103
B.28.5
C.75
D.206​

Answer 1

Step-by-step explanation:

There are 70 people in a class. A student wants to plot these data in a circle.

We need to find the angle should the wedge for barbecue have.

There are 20 such students that like barbecue.

So,

`B=(20)/(70)* 360^(\circ)\\\\B=102.85^(\circ)`

or

B = 103°

It means that 103° on the circle shows the number of students that like barbecue .
