Answer:
1. AB is a diameter. (False)
2. ST, SP and SQ are radii. (True)
3. SQ = 12 cm. (False)
4. PQ is 12 cm. (True)
Step-by-step explanation:
1. AB is not a diameter because a diameter must pass through the center of the circle.
2. ST, SP and SQ are radii because they all meet at the center of the circle.
3. SQ is not equal to 12 cm. SQ is equal to 6 cm because it is a radius.
4. PQ is equal to 12 cm because it is a diameter. Radius = 6 cm. Diameter = 2 × radius = 2 × 6 cm = 12 cm
