Answer:5744.1

Step-by-step explanation:

π=3.14

Radius=r=14

volume of hemisphere=2/3 x π x r x r x r

volume=2/3 x 3.14 x 14 x 14 x 14

Volume=(2x3.14x14x14x14) ➗ 3

Volume=17232.32 ➗ 3

Volume=5744.1

Answer:

11,400

Step-by-step explanation:

\frac{4}{3} \pi \:  {r}^{3}  \\  =  \frac{4}{3}  \times  \frac{22}{7}  \times 14 \times 14 \times 14 \\  =  \frac{4}{3}  \times 22 \times 2 \times 14 \times 14 \\  = 11,498 \\  = 11,400

The sum of two numbers is 14. The first number is 2/5 of the second number. What are the numbers?​
zlopas [31]

Answer:

4 and 10

Step-by-step explanation:

To solve this problem, we need to find all the numbers between 1 and 13 that have a sum of 14. The list is shown below:

1 + 13,   2 + 12,   3 + 11,   4 + 10,   5 + 9,   6 + 8,   7 + 7

Now we must figure out which set of numbers include one number that is 2/5 of the value of the other. We can do that by turning the sets of numbers into fractions as shown below:

\frac{1}{13}\neq \frac{2}{5}

\frac{2}{12}\neq \frac{2}{5}

\frac{3}{11}\neq \frac{2}{5}

\frac{4}{10}= \frac{2}{5}    (answer)

\frac{5}{9}\neq \frac{2}{5}

\frac{6}{8}\neq \frac{2}{5}

\frac{7}{7}\neq \frac{2}{5}
