The question
Question: make a circle graph of yes 60%, no 40%.
yes 60%, no 40%
A circle graph shows the parts of a whole as slices.
The whole circle is 360 degrees.
the whole circle = 360°
1 Each part of 360°
Yes is 60% of the circle.
60% is 0.6.
0.6 times 360 is 216°.
= yes: 60% × 360 = 0.6 × 360 = 216°
Careful!
A percent is out of 100.
Degrees are out of 360.
60% of the circle is 216°.
Careful: not 60% → 60° ✗
No: 40% of 360 is 144°.
= no: 40% × 360 = 0.4 × 360 = 144°
2 Draw the circle graph
We draw a circle and start at the top.
Yes: a slice of 216°, going round like a clock.
Then no, 144°, and so on.
So the slices are yes 216° and no 144°.
= yes 216°, no 144°
3 Check
Let's check: the slices fill the circle: 216 plus 144 is 360.
So the answer is right!
216 + 144 = 360
Let's look back.
First: each part of 360°.
Then: draw the circle graph.
Last: check.
Answer
= yes 216°, no 144°
