Ответ:

≈ 939,8 см².

Пошаговое объяснение:

S = 1/4πd² - площадь круга через диаметр.

S = π · d²/4 = 3,14 · 34,6² / 4 = 3, 14 · 1 197,16 / 4 = 939,77 ≈ 939,8 см².

В тексте пропущены
некоторые слова, которые даны в последней графе таблицы. Ваша задача – вставить
слова по смыслу в текст 'In that case,' said the Dodo ____1____, rising to its feet, 'I move
that the meeting adjourn, for the _____2______ adoption of more energetic
remedies-'

'Speak English!' said the Eaglet. 'I don't know the meaning of half
those __3___ words, and, what's more, I don't believe you do ___4____!' And the
Eaglet bent down its head to hide a smile: some of the other birds ____5____
audibly.

'What I was going to say,' said the Dodo in an _____6_____ tone, 'was,
that the best thing to get us dry would be a Caucus-race.'

'What IS a Caucus-race?' said Alice;
not that she wanted much to know, but the Dodo had ___7____ as if it thought
that SOMEBODY ought to speak, and no one else seemed ____8____ to say anything.

'Why,' said the Dodo, 'the best way to ____9___ it is to do it.' (And,
as you might like to try the thing yourself, some winter day, I will tell you
how the Dodo ____10____ it.)

First it marked out a race-course, in a sort of circle, ('the ___11__
shape doesn't matter,' it said,) and then all the party were placed along the
course, here and there. There was no 'One, two, three, and ____12_,' but they
began running when they liked, and left __13_ when they liked, so that it was
not easy to know when the race was _14___. However, when they had been running
half an hour or so, and were quite dry again, the Dodo suddenly called out 'The
race is over!' and they all crowded round it, panting, and asking, 'But who has
__15__?'

This question the Dodo could not answer without a great deal of ___16___,
and it sat for a long time with one finger pressed upon its __17____ (the
position in which you usually see Shakespeare, in the pictures of him), while
the __18__ waited in silence. At last the Dodo said, 'EVERYBODY has won, and
all must have prizes.'

'But who is to give the prizes?' quite a __19____ of voices asked.

'Why, SHE, of course,' said the Dodo, pointing to Alice with one finger; and the whole party at
once ___20____ round her, calling out in a confused way, 'Prizes! Prizes!' Слова для вставки : away, chorus, crowded, either, exact ,explain, forehead, immediateinclined ,long, managed, off, offended, over ,paused, rest, solemnly, thought, tittered ,won
