Answer:

V\approx 97.7\ m^3

Step-by-step explanation:

-A hemisphere is equivalent to half of a sphere.

- The area of a sphere is given by the formula:

V=\frac{4}{3}\pi r^3

-Given that r=3.6m, the hemisphere's volume can be calculated as:

V=\frac{4}{3}\pi r^3\\\\V_h=0.5\times \frac{4}{3}\pi r^3\\\\=0.5\times \frac{4}{3}\pi \times 3.6^3\\\\=97.7161\approx 97.7\ m^3

Hence, the hemisphere's volume is approximately  97.7\ m^3

Answer:

The story tells of a plain-looking little bird (the Ugly Duckling) born in a barnyard. His brothers and sisters as well as the other birds and animals on the farm tease him for being plain and ugly, so he runs off to live with a flock of wild ducks and geese until hunters shoot down the flock. Alone again, the Ugly Duckling finds a home with an old woman, but her cat and hen also tease him, so he doesn't stay there long.

In his wanderings, the Ugly Duckling comes across a flock of migrating swans, and he wishes to join them but can't because he's too young and can't fly well enough. When winter sets in, a farmer rescues the Ugly Duckling, but the farmer's children and other animals frighten him with their noise and teasing, so again, he flees. He spends a cold and lonely winter hiding in a cave until springtime, when the flock of swans comes to the lake near his hiding place.

When the Ugly Duckling approaches the swans, he's delighted to find that they accept him and treat him like one of them. When he looks at his reflection in the lake, he realizes, to his astonishment, that he's matured into a beautiful swan himself. When the swans fly off from the lake, he spreads his wings and joins them, finally having found a family who accepts him.

lesantik [10]

Answer:

Step-by-step explanation:

To find the area of a semicircle the formula is

\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2

The square

A=a^2=2^2=4m^2\\6.283+4=10.283m^2

A=wl=7*9=63m^2 (rectangle)

A=\frac{ab}{2} =\frac{6*4.5}{2} =13.5m^2\\63+13.5=76.5m^2 (triangle)

Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found. A squirrel hid 40 nuts all together.
koban [17]

Answer:

15 nuts do not get found.

Step-by-step explanation:

Given that Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found.

Total number of nuts squirrel had hidden = 40

Proportion of nuts not found to total = 3/(3+5) = 3/8

Hence out of 40, nuts not found =3/8(40) = 15 nuts.

15 nuts would not be found and 25 nuts would be found if squirrel had hidden in total 40 nuts.

This is because the proportion of found:unfound = 5:3

Hence 25:!5 =5:3 satisfies this

15 nuts are not found.
