Final answer:
To find 3.61 squared, you multiply 3.61 by itself to get 13.0321, which, when rounded to one decimal place, is 13.0. Hence, the answer is 13.0.
Step-by-step explanation:
The question asks to calculate the value of 3.61 squared and then round the result to one decimal place. To find 3.61 squared, you multiply 3.61 by itself which equals 13.0321.
When this value is rounded to one decimal place, it becomes 13.0.When rounding to one decimal place, you look at the second decimal place to decide whether to round up or down.
If the second decimal place is 5 or more, you round up. In this case, the second decimal place is a 3, so you round down, keeping the first decimal place as is.Therefore, the answer to the question is a. 13.0.
To find 3.61 squared and round it to one decimal place, follow these steps: Step 1: Square the number 3.61. Squaring means multiplying the number by itself. So we will do: \[ 3.61 \times 3.61 \] Step 2: The result of the squaring is a number which could have several decimal places. Step 3: We will then round this result to one decimal place. Rounding to one decimal place means we look at the second decimal place. If it is 5 or greater, we round the first decimal place up
If it is 4 or lower, we leave the first decimal place as is. Step 4: After rounding, the result you would get is 13.0. Therefore, the answer is option a. 13.0
