To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

a large square room has an area of 144 m2 . a) find the length of a side of the room. b) how much baseboard is needed to go around the room? c) each piece of baseboard is 2.5 m long. how many pieces of baseboard are needed?

Answers

Part (a)

area = (side)^2

side = sqrt(area)

side = sqrt(144)

side = 12 meters

==============================

Part (b)

perimeter = 4*(side)

perimeter = 4*12

perimeter = 48

Therefore, you'll need 48 meters of baseboard.

===============================

Part (c)

n = number of pieces

2.5n = total length of all n baseboards

2.5n = total perimeter

2.5n = 48

n = 48/2.5

n = 19.2

Round this up to the nearest whole number. Do not round to n = 19 as that value is too small. Note how 2.5n = 2.5*19 = 47.5 meters, which is 0.5 meters short of the goal of 48 meters.

But if n = 20 then 2.5n = 2.5*20 = 50 meters. We'll have 2 extra meters of baseboard.

Therefore, you need 20 pieces of baseboard.

===============================

Answers:

(a) side length = 12 meters

(b) 48 meters of baseboard

Final answer:

The length of a side of a room with an area of 144m^2 is 12m. The total amount of baseboard needed is the perimeter, which is 48m. If each piece of baseboard is 2.5m, then you would need 20 pieces to cover the room.

Explanation:

The area of a square is calculated by squaring the length of one of its sides. Therefore, if the area is 144m2, the length of one side can be found by taking the square root of the area, which is 12m.

Baseboard is usually required to be placed around the entire room, so you'd need to find the perimeter of the square. The perimeter of a square is four times the length of one side, therefore, 12m x 4 = 48m.

As for the number of baseboard pieces, each piece is 2.5m long. So the total number of pieces needed would be the total length of baseboard (48m) divided by the length of each piece (2.5m). This equals 19.2, but since you can't use 0.2 of a piece, you'd need to round up, resulting in 20 pieces being needed.

What is the side length of a cube with a volume of 3375 cm3

Answers

If you would like to know what is the side length of a cube with a volume of 3375 cm^3, you can calculate this using the following steps:

a ... side of a cube
V = a^3
3375 = a^3
a = 15 cm

The correct result would be 15 cm.

The volume of a cube is given by V = s3, where s is the length of a side. Find the length of a side of a cube if the Volume is 1000 cm3.

If the sixth term of a sequence is 128 and the common ratio is 2, then what is the first term?1
2
4

Answers

Answer: The first term of the sequence is 4.

Step-by-step explanation:

Let a be the first term of the sequence,

Here, the common ratio of the sequence is 2,

Thus, the sequence is,

a, 2a, 4a, 8a, 16a, 32a, .............., so on,...

Since, the sixth term of the sequence = 32a

According to the question,

32 a = 128

⇒ a = 4

Thus, the first term of the sequence is 4.
