Do you know how to round numbers to required level of accuracy

((3.14200 * 1.95) / 6) * ((3 * (5.44^2)) + (1.95^2))

Round the answer to the required level of accuracy, given the fact that each number other that those to be ignored, has been obtained by measurement.

Ignore: power 2, divisor 6, multiplier 3.

Thanks.

94.5414360 must have three significant figures (approximately 94.5 is the answer) since 1.95 and 5.44 and 1.95 all are measured values and only have three significant figures.
