Answer:
Total Surface Area of Solid = C.s.a of hemisphere+C.s.a of cone+C.s.a of Cylinder
slant height of cone=√h²+r²
=√6²+8²
=√100
=10cm
height of cone = 10 cm
radius of hemisphere =radius of cone=radius of cylinder=8cm
T.S.A of solid=2πrh+2πr²+πrl
=πr[2h+2r+l]
=3.14*8[2*10+2*8+10]
=25.12[36+10]
=25.12*46
=1155.52 cm²

Cross-sectional study
Explanation:
When doing research, there are many types of studies. One of these type of studies is the cross-sectional study which consists on gathering data from an population at a specific point in time. The population can consists of people from different ethnicities, ages or characteristics but the main idea is to gather the data at one specific moment.
In this example, a researcher wants to study how anxiety is experienced by people of different ages and interviews depressed people in their 30's, 50's, 70's, adolescents and young adults. We can see that<u> the researcher is gathering data from the population at a specific moment in time.</u> Therefore, this is an example of cross-sectional study.
