What is the area of a circle that has a diameter of 10 inches if using 3.14 for pi?
Correct Answer
D. 78.5 Square Inches
Explanation
The area of a circle can be calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the diameter is given as 10 inches, so the radius would be half of that, which is 5 inches. Plugging this value into the formula, we get A = 3.14 * 5^2 = 3.14 * 25 = 78.5 square inches.

Which is longest?
Correct Answer
C. 1 Meter
Explanation
The question is asking for the longest measurement among decimeter, centimeter, meter, and millimeter. The correct answer is 1 meter, as it is the largest unit of length compared to the other options. A decimeter is 1/10th of a meter, a centimeter is 1/100th of a meter, and a millimeter is 1/1000th of a meter. Therefore, 1 meter is the longest measurement among the given options.

Which is longer?
Correct Answer
B. 1 Kilometer
Explanation
A kilometer is longer than a hectometer, dekameter, and meter. The prefix "kilo-" denotes a factor of 1000, so a kilometer is equal to 1000 meters. In comparison, a hectometer is equal to 100 meters, a dekameter is equal to 10 meters, and a meter is the base unit of length in the metric system. Therefore, a kilometer is the longest unit of measurement among the options given.
