Answer:

6283.2

Step-by-step explanation:

$V=\pi r^{2} h$

= $=\pi *10^{2} *20$

=6283.18531

=6283.2(correct to the tenths place)

Answer:

6,283.2 in^3

Step-by-step explanation:

The volume formula for a cylinder is V = (pi)r^2*h

and in this case r = 10 in, h = 20 in

so the volume of this cylinder is

V = 3.14159(10 in)^2*(20 in) = 6,283.2 in^3

Answer:

D. delete all the layers created and retain only the final layer

Step-by-step explanation:

CAD (Computer aided design) drawing is used in designing 2 and 3 dimensional drawings. It uses some computer software such as the C++ programming which supports custom objects. It was also one of the earliest forms of computer aided design programs that could be used on personal computers.

The final steps in the CAD drawing involves the deletion of all the extra layers created as a result of measurements, and the retention of only the final layer. This final layer would give us the real shape we need,

Solve x – 7 > –8.

IgorC [24]

Question 1.

x - 7 > - 8

Adding 7 to both sides, we get:

x - 7 + 7 > - 8 + 7

x > -1

Thus the answer to the inequality is option Fourth.

Question 2.

A number exceeds 66. Let that number be x. The number exceeds 66 means that the number is larger than 66. So in form of an expression we can write the inequality as:

x is greater than 66

x > 66

So, option 1st gives the correct answer.

Question 3.

The tiles are square shaped and area of a square can be calculated as the square of its Length.

Area of square = (Length)²

If we are given the Area, we can find the length as:

Length = $\sqrt{Area}$

For Tile A, the length will be:

$Length= \sqrt{9}=3$
So length is a Rational number

For Tile B, the length will be:

$Length= \sqrt{25}=5$
So length is a Rational number

For Tile C, the length will be:

$Length= \sqrt{34}$
So, Length is not Rational.

For Tile D, the length will be:

$Length= \sqrt{76}$
Length is not Rational

Thus, the lengths of Tile A and Tile B are rational only.

Therefore, the correct answer is 1st option
