Which of the following is the surface area of the right cylinder below?

Mathematics

Snowcat [4.5K]3 years ago
8 0

Answer: Option A.

Step-by-step explanation:

You need to use this formula for calculate the surface area of the right cylinder:

SA=2\pi r^2+2\pi rh

Where "r" is the radius and "h" is the height.

You can identify in the figure that:

r=8units\\h=3units

Knowing this, you can substitute these values into the formula SA=2\pi r^2+2\pi rh, therefore you get that the surface area of this right cylinder is:

SA=2\pi (8units)^2+2\pi (8units)(3units)

SA=176\pi\ units^2

Kristen just deposited $6,500 into a new bank account that pays 4.5% interest the first year and 3% compounded annually each yea
vladimir2022 [97]

This question is about compound interest, but since the interest is such a small number you can use what you know about simple interest to eliminate some answers.

You can immediately eliminate choice A as a clunker, since it is less than the original amount in the account.

Consider what the amount of interest would be if you make the rate much larger than the original rate, say 10%, or 0.1:

$6,500 × 0.1 = $650

If this amount were added to the original amount each year for two years, the total would be:

$6,500 + $650 + $650 = $6,500 + $1,300 = $7,800

This is an over-estimate for the information given, and since choices C and D are even greater than this over-estimate, they can be eliminated. That means choice B is the correct answer.

At the city museum, child admission is $5.20 and adult admission is $9.50. On Friday,133 tickets were sold for a total sales of
fredd [130]

Answer:

55 adult tickets were sold on Friday.

Step-by-step explanation:

A linear system will be used to model the system.

Let c be the number of child tickets and a be the number of adult tickets

Then according to given statements

a+c = 133\ \ \ \ Eqn\ 1\\9.50a+5.20c = 928.10\ \ \ Eqn\ 2

From equation 1

a = 133-c

Putting this in equation 2

9.50(133-c)+5.20c = 928.10\\1263.5-9.50c+5.20c=928.10\\1263.5-4.3c = 928.10\\-4.3c = 928.10-1263.5\\-4.3c=-335.4\\\frac{-4.3c}{-4.3} = \frac{-335.4}{-4.3}\\c = 78

Putting c = 78 in equation 1

a+78 = 133\\a = 133-78\\a = 55

Hence,

55 adult tickets were sold on Friday.
