Answer:
251.20 cm square
Step-by-step explanation:
As given in figure
height of cylinder = 2 cm
radius of cylinder = 8 cm
lateral surface area of cylinder is given by =
where r is the radius and l is the height
Therefore, lateral surface area of given cylinder
area of base is give by
since there is only one base area of that base
=
Thus,
Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
Answer:
(507.05, 592.95)
Step-by-step explanation:
Given data:
sample mean = $550, sample standard deviation S = $60.05
95% confidence interval , n = 10
For 95% confidence interval for the mean
mean ± M.E.
where M.E. is margin of error =
Substituting the values in above equation
= 2.62×18.99
=42.955
= 550±42.95
=(507.05, 592.95)
