Question

Evaluate. Write your answer as an integer or as a decimal rounded to the nearest hundredth. sin 16° = ___

Answer 1

We have round of to 100th place means up to 3 places

`\sin (16\text{ degre}e)=0.27563`

Now we will reduce the digit from right side upto 3 places

As last digit is 3 which is less than 5 so it will remove directly

`\sin (16\text{ degr}e)=0.2756`

Now the last digit is 6 which is greater than 5. So and is even so change we will simply remove this

`\sin (16\text{ degre}e)=0.275`
