1. B

2. D

3. C

4. None of the provided options

5. C

6. A

7. C

8. C

9. None of the provided options

10. D

1. The formula for finding the area of a circle is A = πr². So, the correct answer is B. A = r².

2. The symbol π represents the mathematical constant pi, which is approximately equal to 3.14. So, the correct answer is D. π = 3.14.

3. The area of a circular door mat with a radius of 10 cm is calculated as A = πr² = π(10)² = 314 sq. cm. So, the correct answer is C. 314 sq. cm.

4. The area of the base of a cylinder with a diameter of 10 cm (which means the radius is 5 cm) is calculated as A = πr² = π(5)² = 78.5 sq. cm. None of the provided options match this answer.

5. The area a circular rug with a radius of 20 cm occupies on the floor is calculated as A = πr² = π(20)² = 1256 sq. cm. So, the correct answer is C. 1,256 sq. cm.

6. The appropriate cubic unit of measure for a Rubik's cube would be cubic centimeters (cu.cm) because a Rubik's cube is a small object. So, the correct answer is A. cu.cm.

7. The best cubic unit of measure for a classroom, which is a large space, would be cubic meters (cu.m). So, the correct answer is C. cu.m.

8. The volume of a cube whose edge measures 20 centimeters each is calculated as V = edge³ = (20)³ = 8,000 cu.cm. So, the correct answer is C. 8,000 cu.cm.

9. The formula for finding the volume of a cube is V = edge³. None of the provided options match this formula.

10. There are 1,000,000 cubic centimeters in 1 cubic meter. So, the correct answer is D. 1,000,000.
