2. What is the volume of the metal in this heavy-duty pipe? (It is not drawn to scale and the inside of the pipe is empty space.) Show all work and be sure to label your answer. Use 3.14 to estimate pi.

Answers

Answer 1

Answer: Volume of the outer cylinder = 3.14 x (1.5)² x 18 = 127.17 ft²

Volume of the inner cylinder = 3.14 x (1)² x 18 = 56.52 ft²

Volume of the pipe = 127.17 - 56.52 = 70.65 ft²

Answer: 70.65 ft²

Matilda is filling a circular section of her porch with colorful pebbles. She knows the diameter of the circular section is 15ft, and each bag of pebbles covers 10ft. How many bags of pebbles will Matilda need? A. 15 bags B. 16 bags C. 17 bags D. 18 bags

Answers

Answer:

D. 18 bags

Step-by-step explanation:

Given:

Matilda is filling a circular section of her porch with colorful pebbles.

Diameter of circular section = 15 feet.

Each bag of pebbles covers 10 square feet.

Question asked:

How many bags of pebbles will Matilda need?

Solution:

Diameter of circular section = 15 feet

Radius, r = $(Diameter)/(2)=(15)/(2) =7.5\ feet$

$Area\ of\ circular\ section=\pi r^(2)$

$=(22)/(7) *7.5*7.5=(1237.5)/(7)=176.78} \ square\ feet$

10 square feet is covered by number of bag of pebbles = 1

1 square feet is covered by number of bag of pebbles = $(1)/(10)$

176.78 square feet is covered by number of bags of pebbles =

$(1)/(10)*176.78=17.67$

We found up to 17 bags of pebbles there is still some place left to fill the section:-

Thus, Matilda need about 18 bags of pebbles to fill the circular section of her porch.

Step-by-step explanation:

|n/6| + 1 = 1

Subtract 1 from each side

|n/6| + 1-1 = 1-1

|n/6| =0

Since this is equal to zero what is inside the absolute value must equal zero

n/6 =0

n =0

Answer:

B) {0}

Step-by-step explanation:

Let's go step by step

|n/6| + 1 = 1

First step is to subtract 1 from both sides:

|n/6| = 0

Now, we can multiply both sides by 6:

n = 0
