The length of the line calculated by using 3 / 8-inch strip will be ( 3/8 )x
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The total amount of line that the line will have depends on the number of strips, and the result is equal to the multiplication of the number of strips, x, and the length of the strips by 3/8 inch
Total length = ( 3/8 )x
where x is the number of strips, and the total length is in inches
Therefore the length of the line calculated by using 3 / 8-inch strip will be ( 3/8 )x.

B. All rectangles are squares
C. All rhombuses are squares
Answer: Option 'A' is correct and true.
Step-by-step explanation:
Square is the quadrilateral whose all sides are equal and all angles are right angles and
Rectangle is the quadrilateral whose opposite sides are equal and all angles are right angles.
so, All squares are rectangle as it satisfied the angle property of rectangle and opposite sides of square is also equal.
But all rectangles can't be a square as in rectangle all sides are not equal.
And all rhombus can't be squares as in square all angles are of right angles but rhombus does not possess such property at all.
Hence, Option 'A' is correct and true.
The formula to get the circumference is 2πr, π being pi and r being your radius.
Your r is 0.9 since the radius is half the diameter.
2πr = 2 x 3.142 x 0.9
= 5.6556cm
≈ 5.7cm
