- Find the surface area when r is 8 inches and h is 8 inches.
A. 160π in²
B. 154π in²
C. 288π in²
D. 256π in² ☑
We are given –
⇢Radius of cylinder , r = 8 inches
⇢ Height of cylinder, h = 8 inches.
We are asked to find surface area of the given cylinder.
Formula to find the surface cylinder given by –
Now, Substitute given values –
- Henceforth,Option D is the correct answer.
Answer:
Which means that this equation is also true: 8/9 > 1/9
Step-by-step explanation:
Is 8/9 less than 1/9? Is 8/9 smaller than 1/9? These are the same questions with one answer.
To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:
8/9 = 0.889
1/9 = 0.111
Then, we compare the two decimal numbers to get the answer.
0.889 is not less than 0.111.
Therefore, 8/9 is not less than 1/9 and the answer to the question "Is 8/9 less than 1/9?" is no.
Answer:
Sample: few thousand adults
Population: all the adults
Step-by-step explanation:
A sample is a subset of the population, selected randomly.
In this case:
The sample consist of the few thousand adults selected to determine the opinions about the National polls.
The population consist of all the adults belonging to the said nation.
Consider an example about the new President election.
To determine which of the two candidates (say <em>A</em> and <em>B</em>) has a higher probability of winning the President election, the election society took a random sample of voters and asked who they think will be a better president.
The sample selected will be large enough, probably 10% of the population of all voters.
From this study it can be estimated which candidate has the higher chance of winning.
