a little monkey was sitting on a tree. she was bored and she wanted to eat. she got down the tree and looked through the jungle to find a banana of a mango. but there was no fruits and even no tasty leafs. she was upset. she wandered through the jungle and meet her friends - green crocodile and bright parrot. parrot was very hungry too because he also couldn't find anything to eat. they decided to walk together. in a minute they noticed a huge yelow banana lying on the floor. monkey clutched it and at once many hunters with guns run to the glade.
friends started to run away. they ran through the bush and high grass and they saved their lives from the crafty hunters
1. При вычисления второй стороны прямоугольника видим, что в сечении получается удвоенный "египетский" треугольник с катетами 6 и 8 и гипотенузой 10 см. Радиус цилиндра R=8., высота = 6 см. Объем цилиндра V = π*R²*H = π*64*6 = 384*π ~ 1206 см³ ОТВЕТ: 384π см³ 2. Для вычисления высоты призмы сначала рассчитаем площадь основания - равностороннего треугольника со стороной а= 2 м Угол между сторонами α= 60 град. Используем формулу S = 1/2*a*b*sin(α) = 2*√3/2 =√3 м² Высота призмы H = S/a = √3/2 м² Объем призмы V= S*H = √3*√3/2 = 3/2 = 1 1/2 м³ ОТВЕТ: 1 1/2 м³

Радиус цилиндра R=8., высота = 6 см.
Объем цилиндра V = π*R²*H = π*64*6 = 384*π ~ 1206 см³
ОТВЕТ: 384π см³
2. Для вычисления высоты призмы сначала рассчитаем площадь основания - равностороннего треугольника со стороной а= 2 м
Угол между сторонами α= 60 град.
Используем формулу
S = 1/2*a*b*sin(α) = 2*√3/2 =√3 м²
Высота призмы H = S/a = √3/2 м²
Объем призмы V= S*H = √3*√3/2 = 3/2 = 1 1/2 м³
ОТВЕТ: 1 1/2 м³
