Question 1:

For this case we have that by definition, the area of a circle is given by:

Where:

r: It is the radius of the circle.

They tell us that the diameter is 9 inches, then the radius is 4.5 inches. substituting we have:

Thus, the area of the circle is

Option C

QUestion 2:

For this case we have that by definition, the volume of a cylinder is given by:

Where:

r: It's the radio

h: It's the height

According to the data we have to:

Substituting in the formula:

Finally, the volume of the cylinder is

Option C

Question 3:

For this case we have that by definition, the volume of a cylinder is given by:

Where:

r: It's the radio

h: It's the height

According to the data we have to:

Substituting in the formula:

Finally, the volume of the cylinder is

Option B

Question 4:

For this case we have that the volume of the bricks comes given by:

The volume of each brick is

On the other hand, we have that the volume of the crate is also obtained by multiplying its three dimensions, that is:

Thus, the volume of the crate is

We divide the volume of the crate between the volume of the brick to know the quantity:

Thus, 80 bricks fit.

Option A

5).  Option C.  63 inches

6). Option C.  2032.71 m³

7). Option b.  145.23 ft³

8). Option a.  80

Step-by-step explanation:

To find the answers

Question 5

Here r = 9/2 = 4.5

Area of circle = πr²

 = 3.14 * 4.5²

 = 63.585 ≈ 63

Option c is the correct answer

Question 6

Here r = 6.8 m and h = 14 m

Volume of cylinder = πr²h

 = 3.14 * 6.8² * 14

 = 2032.71 m²  Option C

Question 7

Here r = 6.8 m and h = 14 m

Volume of cylinder = πr²h

 = 3.14 * 5² * 7.4

 = 145.23 feet²  Option b

Question 8

Volume of one brick = lbh

 = 11 * 5 * 3

Volume of crate = 55*20*12

number of briks = Volume of crate /Volume of one brick

 = (55*20*12)/(11 * 5 * 3)

= 80   Option a

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
