According to the Royal Canadian. Mint Act, a 50-cent Canadian coin must have a diameter of. 27.13 millimeters. What is the ... tenth of a square millimeter? ... nearest square inch of the smallest cover that ... area to the nearest tenth of a meter.
577.8mm
As a Canadian, I haven't seen a 50-cent coin in circulation for years.
Anyway...
I really don't understand what your question is.
The area would be π(13.565^2) mm^2
= appr 578.082.. mm^2
"What is the ... tenth of a square millimeter? "
1/10 square mm = .1 square mm
are you supposed to round off the above answer to a tenth?
then it would be 578.1 mm^2
" nearest square inch " --- we have not used inches since 1972
"nearest square inch of the smallest cover that ... area to the nearest tenth of a meter."
that makes no sense to me
(Furthermore, if you check with your textbook, the spelling in our country would be millimetre, not millimeter.
A millimeter would be an instrument that measures millis, a millimetre is a unit of measurement.
e.g. A speedometer is an instrument that measures speed.
557.8mm
To find the tenth of a square millimeter, we need to divide the diameter in millimeters by 10.
27.13 millimeters / 10 = 2.713 square millimeters
To convert square millimeters to square inches, we need to divide by the conversion factor of 645.16, which represents the number of square millimeters in a square inch.
2.713 square millimeters / 645.16 = 0.0042 square inches (rounded to four decimal places)
To convert square inches to square meters, we need to multiply by the conversion factor of 0.00064516, which represents the number of square inches in a square meter.
0.0042 square inches * 0.00064516 = 0.00000271 square meters (rounded to six decimal places)
Therefore, the tenth of a square millimeter is 2.713, the nearest square inch of the smallest cover is 0.0042, and the nearest tenth of a meter for the area is 0.00000271.
