Calculate the following with the correct number of sig figs. 1.5.00 + 2.1

Carry out the following arithmetic operations. (Enter your answers to the correct number of significant figures.) (a) the sum of the measured values 521, 34.6, 0.90, and 9.0 (b) the product 0.0052 ✕ 425.6 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. (c) the product 17.30 ✕ π
