How many litres of milk can be put in six hemispherical bowl each of diameter 35cm

Lesechka [4]

Answer:

Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.

Step-by-step explanation:

The volume of a hemisphere ( $V$ ), measured in cubic centimetres, is obtained from this formula:

$V = \frac{2\pi}{3}\cdot R^{3}$

Where $R$ is the radius of the hemisphere, measured in centimetres.

We know that radius is the half of the diameter ( $D$ ), measured in centimetres, then:

$R = 0.5\cdot D$

( $D = 35\,cm$ )

$R = 0.5\cdot (35\,cm)$

$R = 17.5\,cm$

Now, we get the volume of each hemispherical bowl:

$V = \frac{2\pi}{3} \cdot (17.5\,cm)^{3}$

$V \approx 11224.649\,cm^{3}$

The total volume of six hemispherical bowl is:

$V_{T} = 6\cdot V$

$V_{T}= 6\cdot (11224.649\,cm^{3})$

$V_{T} = 67347.894\,cm^{3}$

From Physics we know that 1 litre equals 1000 cubic centimetres. Then:

$V_{T} = 67.348\,L$

Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.

Select the correct answer. In which table does y vary inversely with x?

vladimir2022 [97]

Answer: C

<u>Step-by-step explanation:</u>

Varies inversely means xy = k

A. 1(-3) = -3

2(-9) = -18

-3 ≠ -18

B. 1(-6) = -6

2(-12) = -24

-6 ≠ -24

C. 1(6) = 6

2(3) = 6

3(2) = 6

6 = 6 = 6 This works!

D. 1(-3) = -3

2(2) = 4

-3 ≠ 4

The only table that has the same k-value is option C.

What is 12 = -7f-9 ?

sattari [20]

The answer is -3 because you have to add 9 to both sides, then you have to divide by -7 to both sides to get your answer: f = -3
If you are not sure if the answer is right, then plug the answer in the problem to see your answer is correct or not.
