Question

Below is the calculator result for the operations indicated. Enter the answer to the correct number of significant figures for this calculation, using the rules for significant figures.

(4.95960 − 0.0057 + 15) ✕ 3.14 = 62.655246

Answer 1

Significant figures express an answer that is limited in precision by the least precise number in the data.

For this question, that is the 15.

For Addition & Subtraction, you cannot be more precise than the "ones" digit.

For Multiplication and Division, you cannot be more precise than 2 digits.

For more precision (digits) in the result, the 15 would have to be written as 15.000...........

Expressing the answer to 2 digits of precision with appropriate rounding would be = 63.
