Please answer question 12 part A

When making observations using two different instruments, it is important to keep in mind the number of significant figures in the reported measurement. The number of significant figures in a reported measurement indicates the certainty associated with that measurement. The following activity allows you to find the diameter of the circle with two rulers. Click on the image to explore this activity depicting the level of precision available for measurements taken using different scales. Click "Start" and measure the diameter of the blue circle by dragging it to one of the rulers. Enter the diameter using an appropriate number of significant figures and click "Submit." Start I cm 2 cm 3 сm 4 ст 0.000 Submit Ruler A Ruler B I cm 2 cm 3 сm 4 cm uluuluw 0.000 Submit After opening the activity, click the "Start" button, then drag the circle over one of the rulers to find its diameter. Let us consider the ruler at the top as Ruler A and that at the bottom as Ruler B. To count the number of significant figures in a value, use the following rules: 1. Nonzero integers are always significant. For example, 12.34 has four significant figures. 2. Zeros between two nonzero integers are always significant. For example, 1005 has four significant figures. 3. Zeros to the left of the first nonzero digit are not significant. For example, 0.0004 has one significant figure. 4. Zeros before a decimal point and after a nonzero number are significant. For example, 40.1 has three significant figures. 5. Zeros after a nonzero digit are known to be significant if, and only if, the number contains a decimal point. If the number does not contain a decimal point, the zeros are either not significant or are ambiguous. For example, the number 500 has only one significant figure or some may say it has an ambiguous number of significant figures, whereas 500. clearly has three significant figures.
