Answer:

area: 60π cm² ≈ 188.5 cm²
volume: 63π cm³ ≈ 197.9 cm³
doubling the radius

Step-by-step explanation:

The surface area of a right cylinder is given by the formula ...

SA = 2πr(r +h) . . . . . radius r, height h

Filling in the given values, we find the area to be ...

SA = 2π(3 cm)(3 +7 cm) = 60π cm² ≈ 188.5 cm²

The volume of the cylinder is given by the formula ...

V = πr²h . . . . . radius r, height h

Filling in the given values, we find the volume to be ...

V = π(3 cm)²(7 cm) = 63π cm³ ≈ 197.9 cm³

The volume is proportional to r², so doubling the radius will multiply the volume by 2² = 4.

The volume is proportional to the height, so multiplying the height by 3 will multiply the volume by 3.

4 > 3, so doubling the radius gives the most volume

Each of 11 refrigerators of a certain type has been returned to a distributor because of an audible, high-pitched, oscillating n

Pie

Answer:

The correct answer is 1,51%

Step-by-step explanation:

To get the probability equally likely of the first 6 examined that have a defective compressor, we use the following formula

P=# of possibilities that meet the condition / #of equally likely possibilities.

As there are multiple events , and all must be achieve, we multiply the probabilities.

P1=7 / 11

P2=6 / 10

P3=5 / 9

P4=4 / 8

P5=3 / 7

P6=2 / 6

P(x)=7 / 11*6 / 10*5 / 9*4 / 8*3 / 7*2 / 6=0,01515151515

P(x)=1,51%

How to solve in long division 82.14 divided by 6.

omeli [17]

Answer: 13.69

Step-by-step explanation:

$82.14/6=$

Multiply 82.14 by 100 to make it a whole number; since you're modifying the number, you must also multiply 6 by 100 in order to keep it balanced.

$82.14*100/6*100$

$8214/600$

---------------------------------------------------------------------

Let's begin.

8214/600=13.69
