Circles Questions and Answers

1.

Which line is the diameter of this circle?
- A.
  
  RP
- B.
  
  SQ
- C.
  
  RQ
- D.
  
  PQ
Correct Answer
C. RQ

Explanation
The diameter of a circle stretches all the way across, from one edge to the other, crossing through the center point (P). Such a line in this circle is RQ. Therefore, it is the diameter here.

2.

Which point is the center point of this circle?
- A.
  
  Point R
- B.
  
  Point P
- C.
  
  Point Q
- D.
  
  Point S
Correct Answer
B. Point P

Explanation
The center point is the point through which the diameter passes, therefore point P is the center point of this circle.

What is a radius of this circle?
- A.
  
  RQ
- B.
  
  SPQ
- C.
  
  SR
- D.
  
  SP
Correct Answer
D. SP

Explanation
A radius is a line that goes from the edge of the circle to the center point. It is half of the diameter. Among the given options, one such line is SP.

RS is a(n):
- A.
  
  Arc
- B.
  
  Chord
- C.
  
  Center Point
- D.
  
  Radius
Correct Answer
A. Arc

Explanation
An arc is a portion of a curve in a circle. It is defined by two endpoints and the points on the circle between those endpoints. In this context, RS is an arc, because it is a portion of a curve in a circle.

Rate this question:
5.

What is the length of the radius when the diameter is 4 cm long?
- A.
  
  4 cm
- B.
  
  2 cm
- C.
  
  8 cm
- D.
  
  12.56 cm
Correct Answer
B. 2 cm

Explanation
The length of the radius can be found by dividing the diameter by 2, according to the formula for finding the radius of a circle. In this case, the diameter is given as 4 cm, so dividing it by 2 gives us a radius of 2 cm.

Rate this question:
6.

What is the length of the diameter when the radius is 9 m?
- A.
  
  28.26 m
- B.
  
  9 m
- C.
  
  18 m
- D.
  
  56.52 m
Correct Answer
C. 18 m

Explanation
The diameter of a circle is equal to twice the length of its radius. In this case, the radius is given as 9 m. Therefore, the length of the diameter would be 2 times 9 m, which equals 18 m.

Rate this question:
7.

What is the length of the diameter of this circle?
- A.
  
  16 cm
- B.
  
  25.12 cm
- C.
  
  16 m
- D.
  
  8 cm
Correct Answer
A. 16 cm

Explanation
The length of the diameter of a circle is equal to twice the radius. Since the answer given is 16 cm, it can be inferred that the radius of the circle is 8 cm. Therefore, the diameter is 16 cm.

Rate this question:
8.

What is the length of the radius of this circle?
- A.
  
  16 cm
- B.
  
  4 cm
- C.
  
  25.12 cm
- D.
  
  8 cm
Correct Answer
D. 8 cm

Explanation
The length of the radius of a circle is the distance from the center of the circle to any point on its circumference. In this case, the correct answer is 8 cm, which means that the distance from the center of the circle to any point on its circumference is 8 cm.

Rate this question:
9.

Find the circumference.

Correct Answer
50.24 cm

Explanation
The given answer of 50.24 cm is the correct circumference. The question asks to find the circumference, which is the distance around a circle. The given answer is in centimeters, indicating that the measurement is in units of length. Therefore, the correct answer is 50.24 cm, which represents the distance around the circle.

- B.
  
  4
- C.
  
  1
- D.
  
  5
Correct Answer
B. 4

Explanation
There are six radii shown in the given question. A radius is a line segment that connects the center of a circle to any point on its circumference. By counting the number of line segments that meet this criteria, we can determine that there are 4 radii shown.
