Which sampling method divides the population up into sections, randomly selects some of those sections, then chooses all the members from the selected sections to study?
What is Cluster Sampling?
Cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research. Researchers then select random groups with a simple random or systematic random sampling technique for data collection and data analysis.
So, The above mentioned type of sampling is called cluster sampling.
Cluster sampling is a sampling technique in which the entire population of interest is divide into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.

Step-by-step explanation:
The diameter is . . .
d = 2r
d = 2 × 5inch
d = 10 inch
The radius is . . .
r = 5 inch
The circumference is . . .
C = πd
C = 3,14 × 10 inch
C = 31,4 inch

Answer:
78
Step-by-step explanation:
Arc GHJ is 81*2= 162 (the arc measure of an inscribed angle that does not cross the center of the circle is 2 times the measure of the angle
since arc GH is 84 and we need HJ, subtract 84 from 162=78
