Which would be the correct unit of measurement to choose for measuring the length on an ant?
-
Kilometres
-
Metres
-
Millimetres
-
Centimetres
Correct Answer
A. MillimetresExplanation
The correct unit of measurement to choose for measuring the length of an ant would be millimetres. Millimetres are the smallest unit of measurement in the given options and would be most appropriate for measuring the tiny size of an ant. Kilometres and metres are too large to accurately measure the length of an ant, while centimetres are larger than necessary and may not provide precise measurements.Rate this question:

To convert centimetres to metres I do the following.
-
Divide by 100.
-
Multiply by 10.
-
Divide by 10.
-
Divide by 100.
Correct Answer
A. Divide by 100.Explanation
To convert centimetres to metres, you need to divide the given measurement by 100. This is because there are 100 centimetres in 1 metre. By dividing by 100, you are essentially removing the centimetre unit and converting it to metres. The other operations mentioned (multiply by 10 and divide by 10) are not necessary and would not yield the correct conversion from centimetres to metres.Rate this question:

What is the special name for the perimeter of a circle?
Correct Answer
circumferenceExplanation
The special name for the perimeter of a circle is called the circumference. The circumference is the distance around the outer edge of a circle. It is calculated using the formula 2πr, where r is the radius of the circle. The circumference is an important measurement in geometry and is used to calculate various properties of circles, such as the area and diameter.Rate this question:

Choose the correct method for calculating the circumference of a circle with a diameter of 10 cm
-
5 times Pi squared.
-
5×π
-
10×π
-
10 squared time Pi
Correct Answer
A. 10×πExplanation
The correct method for calculating the circumference of a circle with a diameter of 10 cm is by multiplying the diameter by π (pi). The formula for calculating the circumference of a circle is C = πd, where C is the circumference and d is the diameter. In this case, the diameter is 10 cm, so the equation becomes C = π(10) = 10π. Therefore, the correct answer is 10×π.Rate this question:

A farmer has a rectangular paddock with length of 25 m and breadth of 15 m. What is the perimter of this paddock?
Correct Answer
80 m
80m
80 metres
80Explanation
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length is 25 m and the breadth is 15 m. So, the perimeter would be 2 times the sum of the length and breadth, which is 2(25 + 15) = 2(40) = 80 m.Rate this question:
