When you are asked what is the sin of π/6, or 30 degrees, you would look at the special triangle (30-60-90) to see that sin, or opposite over hypotenuse, of π/6 is 1/2. Arcsin, or csc, will present you with the ratio, 1/2, and ask for the angle. It's essentially working the question backwards.

Answer:
The correct answer is 11.1.
Step-by-step explanation:
Given:
Area of square platter .
If side length of square platter is .
Then, .
As per question, .
So, .
Taking square both the sides, =
.
Since the decimal is given in the hundredth position, we can estimate the value to the nearest tenth of a decimal.
Here, the hundredth place has the digit 3.
As 3 is less than 5, we don't add any number to the neighboring digit 1.
So, 3 becomes 0 and the number 11.13 becomes 11.10 and hence 11.1.
Therefore, the correct answer is 11.1
