Convert 11π/6 to degrees

Step by step

The question

Question: change 11π/6 to degrees.

1 Write the rule

Radians are another way to measure an angle.

A half turn is 180°.

In radians, a half turn is π.

So π = 180°.

We divide both sides by π.

One radian is 180° over π.

Careful!

To get degrees, π must cancel.

So π goes at the bottom.

2 Multiply

11π/6 radians is 11π/6 times one radian.

So we multiply by 180° over π.

π on top and π at the bottom: π over π is 1.

Cross them out.

What is left: 11 × 180° over 6.

3 Make it simpler

First 180 divided by 6: 30.

Dividing first keeps the numbers small.

So it is 11 times 30°.

So 11π/6 = 330°.

4 Check

Let's check: go back to radians.

Times π over 180.

We get 11π/6 again.

So it is right!

Let's look back.

First: write the rule.

Then: multiply.

Then: make it simpler.

Last: check.
