Answer:
120 degrees
Step-by-step explanation:
we know that the measure of the arc length of the arc in degrees is 30 degrees we also know that the measure of the angle inside of it is half its size.
Therefore, angle DOA is 60 and it is supplementary to DOC.
180 - 60 = DOC = 120 degrees.
Great question, had to think about and look up some laws.

Answer:
15 cm
Step-by-step explanation:
Given:
The two cylinders shown in the figure are similar to each other.
Therefore, when two figures are similar their measures are in proportion.
So, radius and height of both the cylinders are in proportion.
Radius of both the cylinders are 2 cm and 5 cm respectively. Height of the smaller cylinder is 5 cm. Now,
Doing cross multiply, we get:
Dividing both sides by 2, we get:
Therefore, the height of the larger cylinder must be 15 cm in order to make both the cylinders similar to each other.
