Ineed i struggle on these questions

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

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
