208.81 square centimeters of aluminium are needed
<em><u>Solution:</u></em>
Given that,
Radius = 3.5 cm
Height = 6 cm
We have to find the square centimeters of aluminum needed
So we have to find the surface area of cylinder
<em><u>The surface area of cylinder is given by formula:</u></em>

Where "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the values we get,</u></em>

Thus 208.81 square centimeters of aluminium are needed
Hi,
The answer is c. The sample is biased.
This is because the sample is taken on a single state, an Rebecca reports a statistic about the nation. Her data contains information only of her state. If she lives in a very cold state, there is probably more homeowners using electric heat than in a hot state.

Answer:
$126
Step-by-step explanation:
Given that:
Investment is done as per Simple interest.
Principal = $3000
Time for which the investment is to done = 7 years
Rate of interest = 6%
To find:
Interest earned when the investment matures?
Solution:
Formula for Simple Interest :

Where
is the principal amount
is the Rate of Interest
is the time for which the investment is made
Putting the given values:

Therefore, the answer is:
Interest earned is <em>$126</em>.
The answer is 24 * 10^4
Since we’re asked for a whole number, we count the number of zeros after the first nonzero numbers. In this case, our first non-zero numbers are 2 and 4 (24). The number of zeros after these numbers are four (4). The number of zeros indicates the power number of 10.
Had we been asked for a decimal number and a power of 10, then the answer would have been 2.4 * 10^5
