How many centimeters are there in 90 inches, rounded to the nearest tenth?

To convert inches to centimeters, one must use the conversion factor that 1 inch is equivalent to 2.54 centimeters. To find out how many centimeters are in 90 inches, you multiply 90 by 2.54.

Doing the calculation:

90 inches × 2.54 cm/inch = 228.6 cm.

Next, when rounding to the nearest tenth, you look at the number in the hundredths place. Here, it is '6', which means you round the '2' in the tenths place up to '3', yielding 228.6 cm rounded to the nearest tenth.

Given the answer should reflect the measurement in centimeters, the result indicates that none of the provided choices accurately represent the conversion of 90 inches to centimeters rounded to the nearest tenth as 228.6 cm.
